Release Notes

Updates, improvements, and fixes to BioTrac.

September 29, 2026

New

Weights that match your equipment

BioTrac now raises a weight only when you own it. For each weighted item (dumbbells, kettlebells, barbells and so on), choose "Full range" or list the weights you have. Progression then moves between those real weights, and when you reach the top of your set, the rep range grows instead. Equipment you have not described holds its weight and progresses on reps. You can pick weights right under each item in onboarding and Edit Profile. If any are missing, the app reminds you on launch until you finish or choose Later.

New

Medicine balls

Medicine balls are now on the equipment list. Pick the sizes you own, from 4 to 30 lbs, or choose a standard gym rack. Slam ball and wall ball work can now carry a weight that steps up to your next ball.

Improvement

Plans that respect your equipment

Plan generation, plan edits, and exercise swaps now check every exercise against the equipment you selected, so a bodyweight-only plan no longer includes Goblet Squats or Pull-Ups. Plan templates also no longer assume a full gym. Exercises that BioTrac adds during a plan edit keep their equipment details, and an exercise swapped in gets a weight based on its own equipment.

Improvement

Smarter coaching on a new model

Plan creation, plan edits, the nightly coaching review, and chat now run on Claude Sonnet 5.5.

Bug Fix

Home screen no longer loads twice on launch

Opening the app straight into your plan loaded the Home screen twice. It now loads once, which also removes a duplicate prompt about undescribed weights.

September 24, 2026

Improvement

The "Plan updated" notification says what changed

The notification sent when a plan change finishes now lists the change, for example "Barbell Bench Press: swapped for Dumbbell Floor Press. Added Upper C." If nothing changed, it says "Plan reviewed" instead.

Bug Fix

Updated weights show right away

After you finish a workout, or after the overnight coaching review runs, the app now shows and pre-fills the new weights. Before, the old weights stayed until you restarted the app.

Bug Fix

Coaching summary says "Today"

A summary written earlier today was labeled "Yesterday". Dates now count calendar days, so today reads "Today".

September 16, 2026

Bug Fix

Plan change requests no longer replace your coaching summary

Choosing a reason in the plan change sheet could put that request on the Coaching Insights screen in place of your real overnight summary, and could send a morning notification for a summary that did not exist. It could also crash the screen. Requests now stay separate from coaching feedback.

September 7, 2026

Improvement

Simpler height and weight entry

Height is now entered in feet and inches, and weight in pounds, with no unit toggle. The metric option only converted what you typed before saving, and every screen showed imperial units anyway. Removing it also fixes a rounding problem where saving a profile could shift the stored height slightly; heights first entered in centimeters settle on the nearest inch.

Bug Fix

Weight edits no longer drift

Saving your profile would round a logged weight to the nearest pound and add a history entry dated that day, even if you had only changed your age. Weight still appears on the profile but is now recorded from the weight log alone, so your history matches what you entered.

Bug Fix

Weight history starts from your first entry

Fixed an issue where the starting weight from onboarding and the first entry in your weight history were saved as separate steps. If the second one failed, the weight log looked empty even though your weight was on file. Both are now written together.

September 6, 2026

New Feature

Change your equipment any time

You can now edit your equipment from the Profile screen, using the same picker as onboarding. Equipment used to be collected once and then fixed for the life of your account. If you remove something your current plan relies on, BioTrac offers to replace those movements with alternatives you can do; declining leaves your plan alone.

New Feature

Cardio equipment and conditioning exercises

Treadmill, stationary bike, rowing machine, elliptical, and stair climber are now equipment options, with ten conditioning exercises to match, including separate steady-state and interval entries for the treadmill and bike. Three of them (jump rope, burpees, and mountain climbers) need no equipment, so conditioning is available even if you train with nothing.

Bug Fix

Plan changes know what equipment you own

Fixed an issue where your equipment list never reached BioTrac when you asked for a plan change, and where skipping the equipment step during onboarding was read as having a full gym. Requests tagged as an equipment issue now require every replacement to be one you can perform.

Bug Fix

Single-exercise changes use your real numbers

Fixed an issue where changing one exercise sent your current weight, rest time, and position in the workout as blank values, so the request was answered without them. The real values are now included.

Bug Fix

Exercises you cannot do no longer appear

An exercise saved without a record of the equipment it needs was treated as needing none, which is how a stair climber turned up in a plan for someone training with dumbbells. A missing requirement now reads as unknown and the exercise is held back, and new exercises must state the equipment they need.

Improvement

Plan changes consider your training history

A request to change your plan now carries your goal, experience level, and recent workouts, not just your coaching tone preferences. If you have been skipping or substituting a movement for weeks, that history is visible when you ask to have it removed. Chat also picks up an equipment change made mid-conversation.

Improvement

Plan change requests stay out of analytics

The reason you give when asking for a plan change is often personal, such as an injury or a pregnancy. That text was being sent to product analytics along with the request and no longer is. It stays stored with your plan, where BioTrac needs it, while analytics records only the category and the message length.

Bug Fix

Clearer messages when a value is out of range

Fixed an issue where entering a height outside the accepted range returned a message about character limits rather than the range itself. Numeric fields now state the smallest and largest value they accept.

September 3, 2026

New Feature

Edit your profile after onboarding

Your age, height, and weight were collected during onboarding and then frozen. The Profile screen now shows all three, with an edit button for your age range and height. Training settings (goal, experience level, days per week) stay read-only, since changing those means rebuilding your plan.

New Feature

Weight tracking over time

BioTrac now keeps a dated record of your weight instead of only the latest number. A Weight button on the History tab opens your log, where you can record a new weight and see a trend chart above every entry you have made, listed by date.

July 1, 2026

Improvement

Coaching summaries describe only what actually changed

Your overnight coaching summary was written before any adjustment was applied, so a change that was suggested but failed to land could still be described as though it had happened. The summary is now written afterward, with the coaching narrative followed by a plain list of the changes that really applied. The Coaching Insights screen counts only applied changes as well, so recommendations no longer inflate the count.

Bug Fix

Cleaner plan update notifications

Fixed an issue where the push notification announcing a plan summary could show raw formatting characters such as asterisks and dashes when the text was shortened to fit. The notification is now flattened to plain text before it is trimmed, and the full summary in the app is unchanged.

Improvement

No more adjustments that change nothing

BioTrac could list an exercise swap among your plan adjustments and then change nothing, because swapping one exercise for another was never implemented. That option is gone. A movement that needs to be scaled back now has its reps or target effort adjusted in place, which is a change you can see in the plan.

June 24, 2026

Bug Fix

Onboarding keeps your age, height, and weight

Fixed an issue where the height and weight you entered during onboarding were collected on screen but never saved, so your first plan was built without them. Both are now stored with the rest of your answers, and the same screen asks for your age range, which BioTrac had no way to collect before.

June 20, 2026

New Feature

Reorder exercises in a workout

You can now change the order of exercises on the Workout Overview screen. Enter reorder mode, drag exercises into the sequence you want, and BioTrac saves the new order for future workouts.

June 19, 2026

Bug Fix

Feedback notes stay above the keyboard

On smaller phones or with larger display scaling, the notes field in the "How was this exercise?" prompt could sit behind the keyboard. The notes input now scrolls into view when you tap it, and the sheet gives it more room.

June 17, 2026

Improvement

Copy text from chat

You can now select and copy text in the chat. Long-press any of your messages or BioTrac's replies to highlight text and copy it, the same way you would in any other messaging app.

Bug Fix

Apple purchases activate reliably

Fixed a rare case where an iOS subscription could be charged by Apple but not activated in the app because the purchase came from a different App Store environment than expected. Purchases and renewals now verify and activate correctly regardless of environment.

Bug Fix

More reliable Restore Purchases on iOS

Fixed an issue where Restore Purchases could fail entirely if one subscription product could not be found, for example after a product was renamed. Each product is now checked independently, so a single lookup problem no longer blocks restoring your subscription.

June 10, 2026

New Feature

History tab

A new History tab has been added to the bottom navigation. It shows your average RPE over the last 30 days as a visual gauge, trend charts for training volume, RPE, weekly frequency, and session duration, and a per-exercise progress section with weight-over-time charts. Below the charts, your past workouts are listed by week with infinite scroll and pull-to-refresh. Tapping any workout opens a detail view showing every set you logged along with estimated one-rep max values.

June 9, 2026

New Feature

Set your own timezone and notification times

BioTrac used to send workout reminders and the overnight coaching summary on a fixed Eastern-time schedule. Now you can choose your own timezone and the times you receive your morning workout reminder, your evening workout reminder, and your overnight coaching summary. Everything is set from the Notifications section of the Profile screen. BioTrac detects your device's timezone automatically the first time, and each time can be adjusted in 15-minute increments.

Bug Fix

Reliable notification settings on Profile

Fixed a crash that could appear on the Profile screen when opening your notification settings. The settings now load reliably and fall back to sensible default times if any value is missing.

May 27, 2026

New Feature

Coaching summaries delivered by morning notification

BioTrac analyzes your recent workouts overnight and generates a coaching summary with any plan adjustments. You now receive a push notification at 8 AM when a new summary is ready, so you never have to open the app to find out. Tapping the notification takes you directly to the Feedback Insights screen. A new toggle in Profile lets you opt out if you prefer not to receive these notifications.

Bug Fix

Coaching summary notification now opens the right screen from a cold start

Tapping a coaching summary push notification when the app was fully closed would land on the Home screen instead of Feedback Insights. The notification now correctly navigates to the coaching summary regardless of whether the app was open, backgrounded, or closed.

Bug Fix

Keyboard no longer covers the workout complete screen

Fixed two issues on the workout complete screen where the iOS keyboard would cover the feedback input field and push the Finish Workout button out of view. Both elements now stay visible and reachable while the keyboard is open.

May 21, 2026

New Feature

Trial expiration reminders

BioTrac now sends a push notification and email about two days before your free trial ends, and another when it expires. Each notification is sent once so you are not spammed, and tapping the push takes you directly to the subscription screen.

May 17, 2026

New Feature

Plan updates delivered by push notification

Generating or modifying a plan no longer keeps you on a loading screen for several minutes. BioTrac now runs the work in the background and sends a push notification when your plan is ready. You can close the app, use other apps, or lock your phone while your plan generates.

Improvement

Smarter push notification prompt during onboarding

The request for push notification permission now appears during plan generation with a brief explanation of why it helps, instead of appearing cold at signup with no context.

Improvement

Plan modification status visible on Profile

The Profile screen now shows an "Updating Your Plan" banner whenever a modification is in progress, so you always know where things stand without opening the modification modal.

Improvement

App resumes correctly after closing during plan generation

If the app is closed or backgrounded while a plan is being generated, it now picks up where it left off when you reopen it, instead of sending you back to the beginning of the onboarding wizard.

May 3, 2026

New Feature

Workout reminder notifications

BioTrac can now send workout reminders for training days on your active plan for workouts you haven't completed yet. They help you stay on track without having to check the app first.

Improvement

Notification controls in Profile

The Profile screen now includes a Workout reminders toggle under Notifications. You can turn reminders on or off from the app, and BioTrac will ask for push notification permission when reminders are enabled.

Bug Fix

More reliable reminder setup

Fixed a setup issue where enabling workout reminders could fail to register the device for push notifications. Reminder delivery also handles edge cases more gracefully when a scheduled workout needs a fallback match.

May 2, 2026

Bug Fix

Smoother chat typing on mobile

Improved how the chat composer responds to the iOS keyboard. The message box now stays visible with cleaner spacing while you type, reducing awkward gaps and blocked input at the bottom of the Chat screen.

May 1, 2026

New Feature

Intelligent Chat

BioTrac now has an intelligent chat companion in the mobile app. Ask questions about your plan, your recent workouts, or general training advice and get thoughtful, context-aware responses. The chat knows your profile, your active plan, and your last week of workout history. Start a new chat from the Chat tab whenever you want to dig deeper into your training.

Bug Fix

Plan modification retry lockout

Fixed an issue where tapping Modify Plan while a modification was already in progress would show a generic "API request failed" error instead of explaining what was happening. You will now see a clear message that a modification is already running, and the app will automatically pick up the result when it completes.

Improvement

Better plan modification feedback

The modify plan screen now shows errors in a sticky banner that stays visible as you scroll, auto-scrolls to the top when a new error appears, and recovers gracefully when a modification is still running in the background. If polling times out before the AI finishes, the app now lets you know BioTrac is still working instead of treating it as a failure; reopening the modal picks up the completed result automatically.

Improvement

Fewer plan modification validation failures

Added stricter prompting rules to prevent the AI from sending empty or null values for exercise substitutions, which was a common source of validation rejections. Additional context fields are now capped at 2,000 characters to match what the model can reliably handle.

April 30, 2026

Bug Fix

Plan generation and modification reliability

Fixed an issue where generating or modifying a plan could repeatedly fail for some users. Bodyweight, isometric, and rehab exercises were being rejected because they have no weight increment, and a small number of malformed AI responses were slipping through unchecked. BioTrac now accepts zero-increment exercises, enforces stricter constraints on the model, and automatically retries with corrective feedback if the first response is invalid.

Improvement

More accurate workout feedback and exercise edits

The same corrective-retry safeguards now apply to weekly feedback analysis and individual exercise modifications. If the AI returns a malformed response, the system retries with tighter constraints instead of accepting the bad result, so adjustments to your plan stay accurate.

Improvement

Sturdier Apple subscription handling

BioTrac now handles a wider set of Apple subscription events, including refund reversals (which restore access automatically) and Apple-issued renewal extensions (which push your renewal date forward). Duplicate notifications from Apple are also deduplicated, preventing rare cases where a single billing event could be processed twice.

Improvement

Welcome email an hour after signup

New users now receive a welcome email about an hour after creating their account, with a quick orientation to BioTrac and tips for getting the most out of your first plan.

Improvement

Spam-folder reminder on email verification

The verification code screen on the mobile app and the website now reminds you to check your spam or junk folder if your code does not arrive, cutting down on confusion when an email provider misroutes the message.

April 23, 2026

Improvement

Copy workout stats to clipboard

The share button on the workout complete screen now copies a formatted text summary of your workout (sets, reps, weight, and stats) to your clipboard, so you can paste it into any app. Previously the button generated an image and opened the system share sheet, which was slower and less flexible.

April 20, 2026

Improvement

More resilient to backend outages

The mobile app now handles brief server outages more gracefully. Network requests time out after 15 seconds instead of hanging indefinitely, and you stay signed in during temporary connection issues instead of being bounced back to the Welcome screen. The app is also less likely to be terminated by iOS for a slow startup when the backend is briefly unreachable.

April 6, 2026

Improvement

Subscribe before your trial ends

If you want to lock in a plan before your 14-day free trial expires, you can now do that from either the mobile app or the website. The Manage Subscription screen and the account page both show a "Subscribe Now" option for trial users. Previously, you had to wait until the trial ended to pick a plan.

April 5, 2026

New Feature

In-app purchases on iOS

iPhone users can now subscribe to BioTrac directly through Apple using StoreKit. Monthly and annual plans are available in the app, purchases are billed through your Apple ID, and a Restore Purchases button brings back prior subscriptions. Paying on the BioTrac website is still available as a secondary option on iOS.

Improvement

Manage your website subscription without leaving the app (iOS)

If you subscribed through the BioTrac website, the iOS app now opens the billing portal in an in-app browser so you can update payment details or cancel without jumping out to Safari. iOS users now have the same in-app Polar management experience that Android users have had.

Improvement

Automatic recovery for failed iOS purchases

If Apple charges you but the app briefly fails to confirm the purchase, the paywall now automatically looks up your entitlement and activates the subscription instead of showing an error. Deferred purchases (such as "Ask to Buy" for family accounts) are also handled correctly.

April 3, 2026

Bug Fix

Plan modifications timing out

Fixed an issue where asking BioTrac to modify your plan could time out on slower connections, since the request could take 30 to 60 seconds for the AI to generate changes. Plan modifications now run in the background with progress polling, matching how initial plan generation already worked. The modal shows animated progress steps while you wait.

April 1, 2026

New Feature

Accounts and billing on the website

You can now sign in, create an account, and manage your subscription directly on the BioTrac website. The new account page shows your subscription status, lets you pick a plan, start checkout, cancel or reactivate, and open the full billing portal. The sign-in and forgot-password flows on the web match the mobile app.

New Feature

Sign in with Apple on the website

The website now supports Sign in with Apple alongside Google and email, using a separate Apple Services ID configured for the web. If you already have a BioTrac account with the same email, your Apple account is linked automatically.

New Feature

14-day free trial for every new account

Every new BioTrac account now starts with a 14-day free trial automatically, whether you sign up with email, Google, or Apple. No payment method is required up front. When the trial ends, the app prompts you to pick a plan.

Improvement

Paywall refreshes after you subscribe on the web

If you subscribe through the website from a link in the mobile app, the paywall now detects your new subscription when you return to the app, with no need to restart. An "I've Subscribed" button on iOS lets you force a check if needed.

March 30, 2026

New Feature

Blog

The BioTrac website now has a blog with articles covering workout science, nutrition, recovery, and how adaptive training works. You can find it in the navigation bar or at biotrac.org/blog.

Improvement

Updated landing page

The landing page now better explains how BioTrac replaces a personal trainer at a fraction of the cost. We also improved accessibility and search engine optimization across all website pages.

Bug Fix

Mobile menu links scrolling to wrong position

Fixed an issue on the website where tapping a link in the mobile navigation menu would scroll to the wrong section of the page. Links now scroll to the correct position.

March 29, 2026

New Feature

Push notifications

BioTrac can now send push notifications to your device. The app automatically registers for notifications when you sign in and unregisters when you sign out. This lays the groundwork for workout reminders, plan updates, and other timely alerts.

New Feature

Sign in with Google

You can now sign in using your Google account with the new “Continue with Google” button on the sign-in screen. If you already have a BioTrac account with the same email address, your Google account is linked automatically — no need to create a new account. Google-only accounts don’t require a password.

Improvement

Account deletion now removes billing data

When you delete your account, BioTrac now also deletes your customer record from the billing provider. Previously, the billing-side data could remain after local account deletion.

Improvement

Website redesign with app screenshots

The BioTrac website has been redesigned with a cleaner layout, real app screenshots, and optimized images for faster loading. The site is now verified with Google Search Console for better discoverability.

Bug Fix

Plan generation timing out

Fixed an issue where generating a workout plan could time out on slower connections, leaving users stuck on the loading screen. Plan generation now runs asynchronously with progress polling, so the request no longer needs to complete in a single round trip.

Improvement

Animated plan generation loading screen

The plan generation screen now shows animated progress steps so you can see exactly what BioTrac is doing while building your personalized workout plan.

Bug Fix

Google sign-in not loading subscription status

Fixed an issue where signing in with Google (or regular login) would not load your subscription status, which could block access to features you had already paid for. Your subscription is now correctly loaded on every sign-in.

Bug Fix

New users blocked from generating a plan

Fixed a routing issue where new users who completed onboarding could receive a 403 error when generating their first plan. The app now correctly directs new users through the paywall before plan generation begins.

Bug Fix

Google sign-in skipping onboarding

Fixed a bug where a failed Google sign-in attempt could incorrectly allow navigation to the onboarding wizard without being fully authenticated. The sign-in flow now properly validates authentication before proceeding.

Bug Fix

Avatar upload failing for some image types

Fixed an issue where uploading a profile photo could fail silently for certain image formats. The app now correctly detects the image type and shows a clear error message if the upload fails.

March 23, 2026

Improvement

Security updates

Patched 52 security vulnerabilities across backend dependencies. These updates harden the server against known exploits and keep your data safe. No action is needed on your end.

March 20, 2026

Bug Fix

Keyboard covering input fields on Physical Stats screen

Fixed an issue during onboarding where the keyboard would cover the input fields on the Physical Stats screen, making it difficult to see what you were typing. The screen now scrolls properly to keep inputs visible above the keyboard.

Bug Fix

Home screen only showing 3 workouts

The Home screen was incorrectly limited to displaying only 3 workouts from your plan, even if your plan had more. All workouts in your plan are now shown.

Improvement

Smarter split-type handling during plan modifications

Added guardrails to ensure workout split types stay consistent when the AI modifies your plan. If the AI adds workouts that don’t match the declared split pattern, the system now auto-corrects the split type instead of leaving the plan in an inconsistent state.

March 17, 2026

Bug Fix

Customer portal crash for free users

Fixed a crash when users without a subscription tried to access the customer portal. The app now shows the portal link only for users with an active, trialing, canceled, or past-due subscription. Stale billing records are also cleaned up automatically.

Bug Fix

Checkout showing wrong product prices

Fixed a product ID mismatch that caused “Invalid product ID” errors during checkout. The mobile app now fetches the product catalog from the backend dynamically instead of relying on hardcoded values that could drift out of sync.

Bug Fix

Checkout cancel button not working

Fixed an issue where canceling out of the checkout flow would not redirect back to the app. The cancel URL is now correctly passed to the billing provider so the back button and cancel actions work as expected.

Improvement

One-click email unsubscribe

All marketing and update emails now include a one-click unsubscribe link that complies with RFC 8058 requirements. Gmail and Yahoo will show a native unsubscribe button in the email header. Security-related emails (verification, password reset) are not affected.

March 13, 2026

New Feature

Subscription billing with in-app checkout

BioTrac now offers monthly ($9.99/mo) and annual ($99.99/yr) subscription plans, both with free trials. You can subscribe directly within the app using the new in-app checkout — no need to leave the app or visit an external website. A subscription is required to create plans, start workouts, and access workout intelligence features.

New Feature

Subscription management

Cancel, reactivate, or manage your subscription directly from the Profile screen. If you cancel, your access continues until the end of your billing period, and you can reactivate at any time without starting a new checkout. You can also access the full customer portal without leaving the app.

Improvement

Exercise Quick Edit saves all fields

The Quick Edit modal now persists changes to sets, reps, rest time, and RPE in addition to weight. Previously, only weight changes were saved — edits to other fields were silently discarded.

Bug Fix

Feedback screen empty state

Users without workout feedback now see a proper empty state with a Go Back button instead of an error message. The missing-feedback case is no longer treated as an error.

Bug Fix

Subscription reactivation sync

Reactivating a canceled subscription now immediately updates the app to reflect the active status. Previously, a race condition between the backend and the billing provider could leave the screen showing stale data until the app was restarted.

March 4, 2026

Improvement

Smarter exercise matching prevents duplicates

BioTrac now uses fuzzy matching when looking up exercises, so variations like "DB Bench Press" and "Dumbbell Bench Press" correctly resolve to the same exercise instead of creating duplicates. The matching handles common abbreviations, word reordering, and parenthetical formats automatically.

Improvement

Better exercise selection during plan modifications

When restructuring a plan (e.g., changing frequency or split type), BioTrac now references your existing exercise library to avoid creating unnecessary new exercises. Previously, structural plan changes could introduce duplicate exercises because the library context was missing from that flow.

March 4, 2026

Bug Fix

Exercise images failing for certain exercises

Fixed an issue where exercise reference images would fail to load for exercises with special characters in their names, such as parentheses or slashes. Affected exercises like "Explosive Pull-Up (Kipping/Jumping)" now display their images correctly.

Improvement

Improved server stability on shutdown

Resolved occasional errors that could appear in server logs during shutdown. The cleanup process is now more reliable, preventing duplicate resource cleanup attempts.

March 3, 2026

Bug Fix

Stale data after plan modifications

Fixed several cases where the app could show outdated information after modifying a plan. The profile and workouts screens now refresh automatically when you navigate back to them, and in-progress workouts that reference removed exercises are properly cleared instead of causing errors on completion.

Bug Fix

Plan name and description update after restructuring

After restructuring a plan (e.g., switching from a 5-day to a 3-day split), the plan name and description now update to reflect the new structure. Previously they would still show the original text, such as "5-Day Intermediate Muscle Building Split" even after the plan had been changed to 3 days.

Improvement

Plan restructuring support

BioTrac can now handle structural plan changes through the modify plan flow. You can ask to change your training frequency, switch split types, add or remove workout days, and redistribute exercises across your plan.

Bug Fix

Fix crash when changing plan frequency

Resolved an internal server error that occurred when requesting a plan frequency change (e.g., switching from a 5-day to a 3-day plan). A data format mismatch was sending malformed context to a cloud provider, causing the request to fail.

March 1, 2026

Bug Fix

Fix iOS scroll blocking on all screens

Resolved an issue where scrolling would not respond on iOS when starting the gesture on an empty area of the screen. The keyboard dismiss wrapper was intercepting touch events before the scroll view could receive them. Scrolling now works reliably regardless of where you touch.

Improvement

Improved keyboard dismissal across forms and modals

Added scroll-to-dismiss keyboard behavior on all screens with text inputs, including signup, password reset, email verification, account deletion, exercise editing, and plan modification. Previously, the keyboard could only be dismissed by tapping outside an input field. You can now swipe down to dismiss the keyboard naturally.
