FitMax
See where you stand. Train from there.
AI body analysis from your own photos, a training plan built around the result, and a full exercise library — with no account required.
FitMax
See where you stand. Train from there.
FitMax reads a set of body photos and turns them into an honest picture: muscle development by region, symmetry, posture, and an estimated body-fat range. That result becomes the starting point for a training plan built around your goal, your equipment, and the days you can actually train. Alongside it sits an exercise library with demonstration animations and a muscle heat map, plus a workout log that keeps track of what you lifted. There is no sign-up: your profile, your reports, and your workout history stay on your device.
Highlights
An analysis that names the gaps
Photos become region-by-region muscle scores, a symmetry and posture read, and an estimated body-fat range — with the weak points stated plainly rather than buried under a single number.
A plan built on your result
Training days, session length, goal, available equipment, and your analysis feed one generated programme — not a template with your name on it.
An exercise library you can actually navigate
Browse by muscle group on a heat map, see demonstration animations, and log what you lifted as you go.
Your data stays yours
No account, no cloud sync, no ads, no analytics or crash-reporting SDK, and no cross-app tracking. Every connection the app makes is encrypted, and no AI provider key is embedded in the app.

What it collects
No account / anonymous use
There is no sign-in, registration, email, or password. We never create or collect a user ID, and the analysis and plan requests carry no user, device, or session identifier. Identity exists only at the Apple ID (billing) level and as an anonymous subscription profile.
Body photos
The one to three photos you take or pick are resized and sent to the AI provider through our proxy to produce your report. On success, the full-resolution originals are also written to the app's own storage on your device. They are not stored on our servers, and there is no cloud sync — but the app's storage is not excluded from device backups, so they will be included in an iCloud or computer backup if you make one.
On-device measurements
Before your photos are sent, the app uses Apple's Vision framework on your device to estimate shoulder-to-waist ratio, shoulder and hip tilt, arm span, leg-to-torso proportions, and image sharpness. That step uploads nothing — but the resulting numbers are included as text in the analysis request.
Profile & fitness data
Your name, gender, age, height, weight, goal, activity level, training preferences, plans, and workout logs are stored on your device. Your gender, age, height, weight, training experience, and goal are included in the analysis request; when you generate a training plan, your name and a dated summary of your previous reports go with it as well, unless you turn off "use my body analysis" in the questionnaire.
Analysis reports
Each report — scores, estimated body fat, strengths, and advice — is saved on your device along with the paths to its photos. Reports and photos accumulate without a limit and are not cleaned up automatically.
Result cards you save or share
If you save or share a result card, the app builds an image containing your scores and a square crop of your own photo centred on your face, found by on-device face detection. Saving writes it to your system Photos library, where it syncs to iCloud Photos if you have that on and remains after FitMax is deleted. Sharing hands it to whichever app you choose.
Cached exercise media
Exercise animations are cached on your device so they do not download twice. There is no in-app control to clear this cache, and cached filenames encode the source URL, so someone with access to your unlocked device could tell which exercises you had viewed. The exercise detail screen loads animations in an embedded web view pointed at the remote host, which lets that host set cookies in the app's web-content store.
Subscription data
Purchase transactions are handled by Apple and a subscription service, which receives a device identifier (IDFV), IP address, install ID, and device information (model, OS version, language, time zone) tied to an anonymous profile. Card details never reach us.
Built with
Anthropic (Claude)
Analyses your body photos and produces the report. The photos and the accompanying text are sent to this provider through our proxy. Under the provider's published API policy, data sent this way is not used to train its models; that commitment is the provider's rather than something the app can enforce.
Vercel
Hosts our request proxy, which every analysis request passes through so that provider API keys never ship inside the app. The connection is encrypted end to end, but it terminates on this infrastructure, which means your photos pass through it on their way to the AI provider.
Apple
Apple's in-app purchase system processes the auto-renewing subscriptions. Payments are charged to your Apple ID; we never receive or store your card details.
Adapty
Manages subscription state, purchase validation, and premium entitlement through an anonymous device-level profile. Advertising-identifier (IDFA) collection is switched off, so the app does not track you across other companies' apps or websites.
GitHub
Hosts the public exercise database and the demonstration animations. The database is downloaded the first time you open the Training tab, without any action from you, and animations load as you browse. No personal data is attached, but the host sees your IP address as it would for any web request.
