Frequently asked questions about Isofit.

Isofit is a workout tracker for iPhone and the web. You record training by tapping, typing or speaking, a body graph shows which muscles that work reached, and Atlas, a built-in personal AI fitness coach, answers questions about your training. It also has Bonfire, a members-only community feed.

Adults aged 18 and over who want a clearer picture of their training. It is not tied to one style: you can log strength training, cardio, yoga, sports and martial arts, or a mix. You do not need to follow an Isofit program.

It is left open on purpose. Read it as isometric, as "I'm so fit", or as ISO, in search of, fitness. The logo is a cube whose faces spell I, S, O.

Isofit is on the App Store for iPhone (iOS 17.6 or later), and there is a web app at app.isofit.app. There are no native iPad, Apple Watch or Android apps.

Available on the App Store and on the web. Download it from the App Store, or open the web app in your browser.

Tap in sets, reps, weight, distance, time and RPE on each exercise row, type a Quicklog line such as "bench 5x5 225lbs", or hold the microphone and describe the session. A typed line becomes a finished row, and a spoken session becomes a draft you review before it saves.

No. The library has nearly 500 exercises, and you can type any name and create it as a custom exercise, with no limit on how many. Isofit maps custom exercises to muscles so they count on the body graph.

Tap logging and Quicklog work offline, and finished sessions sync when you reconnect. Voice logging and Atlas need a connection.

No. There is no personal-record tracking. History shows every past session and the sets in it.

Yes. Choose metric or imperial for your account and switch units on any row.

A front and back figure shaded by the working sets you logged for each muscle over the last 7, 30 or 90 days or all time. It shows what you train most and what you have been skipping.

No. It counts logged working sets. It does not estimate recovery, readiness or soreness.

Atlas is Isofit's AI coach, a chat assistant for training questions. With personalization on, it reads your logged workouts so its answers reflect your own history. On Pro it can write programs and save them to your routines.

With personalization off, the default, Atlas answers as a general coach and does not read your training history. Turning it on lets Atlas read your recent workouts, keep memory items from your conversations such as goals and preferences, and use your Apple Health daily summaries if you have connected Apple Health.

Withdrawing the opt-in in your account settings deletes stored memory items and stops Atlas reading your training history and Apple Health summaries; Atlas keeps working as a general coach, and messages already sent are not deleted.

No. Atlas is a training and organization tool, not a doctor, physical therapist or substitute for in-person professional care. Injuries, severe pain and symptoms that need diagnosis belong with a qualified healthcare professional.

Yes. Fast, flexible logging is the foundation. Atlas and Bonfire are optional.

Bonfire is Isofit's members-only community feed. A post is a caption, an optional photo and the kind of training it is about, one a day, and members can give kudos and comment. There are no follows, groups or direct messages.

No. Your log is private, and a session appears in Bonfire only if you choose to post it, where all Isofit members can see it.

Logging is free, with no cap on workouts or routines. Pro is $14.99 a month or $124.99 a year in the US App Store and adds the full body graph, 30 Atlas messages a day with deep analysis and saved programs, SITREP (weekly training review), and posting to Bonfire.

Apple processes payments and RevenueCat manages subscription status, so Isofit never stores your full payment card details.

No. Cancelling keeps your account and data; to delete them, use the option in the app's settings or email privacy@isofit.app, after which Isofit keeps only pseudonymized consent records and records the law requires, and may keep anonymized, aggregated data for platform analytics.

Deleting your Isofit account does not cancel an App Store subscription, so also cancel it with Apple: on iPhone, Settings, then your name, then Subscriptions.

Yes, optionally and on every tier. Isofit can read workouts and daily summaries such as steps, exercise minutes, sleep and resting heart rate, and you approve each data type in the iOS permission screen. Isofit never writes to Apple Health, and syncing happens while the app is open.

Isofit uses administrative, technical and organizational safeguards, including encryption in transit and at rest, as described in the Privacy Policy. Workout data is private by default. Isofit does not sell personal information or use your data for advertising.

No. Isofit does not store your precise GPS location.

The weather line is optional, and weather providers receive only a coarse location, such as a zip code, your device location if you enable it, or a city inferred from your timezone, and never your identity or health data.

Yes. You can sign in with Apple, Google, or an email and password, and Google Sign-In is optional.

If you choose it, Google processes your sign-in and shares the account information you authorize with Isofit, under Google's own privacy policy.

No. Isofit's Privacy Policy states that fitness and health data, including anything read from Apple Health, are not used to train AI models. Atlas sends your messages, plus your training context if personalization is on, to its AI provider, OpenAI, to generate replies; processing a request is different from training a model.

Yes. From the app you can export a JSON file of your training, Atlas, account, health and social records, and you can delete your account. Deletion is scheduled after a seven-day grace period.
