Your progress photos deserve better than your camera roll.
Taking the photo is easy. Finding them, lining them up and actually seeing how far you’ve come is not.

- Buried in the gallery→ kept apart, away from cloud backups
- Different framing every time→ the same pose, guided
- Weight in another note→ attached to the day’s photo
The scale often lies; so does the mirror, day to day. Two photos a few weeks apart don’t.
All the tracking. Nothing leaves the phone.
Free, offline, no account. “Visual review”, the AI analysis, is the only premium piece.
Guided photos
A pose and framing guide puts you in the same spot every time, for honest comparisons.
Two dates, lined up
First and latest photo, a milestone, or any two shots: Body Tracker lines them up, side by side or with the slider.
Weight & measurements
Weight, waist, hips, arms: every value is attached to the day’s photo, and the trend reads at a glance.
Regular reminders
Every week, every two weeks: a quiet notification at the pace you choose. Consistency drives progress.
Also: a goal that stays in view, and a 100% offline app — your data lives in a local database, never on a server.
A read on your photos, whenever you ask for it.
“Visual review” analyzes a photo to estimate your body composition — always as a range — and describe your posture. Two photos? It describes the visible change between them. A marker, never a judgment.
- A range, never a single figure.
- Body composition is given as a range, with its confidence level: a visual estimate, not a measurement.
- Posture.
- Shoulder and hip alignment, overall balance: each observation is listed separately.
- Tips for what’s next.
- Two or three generic training, nutrition and recovery tips to guide what comes next — never a prescription.
- Between two photos.
- What changed, area by area, consistency with your logged weight, factual encouragement. Always relative to yourself.
- Over time.
- Every review stays on your phone: the change since the previous one is shown, and a body fat curve appears from your third review.
About 1 minute per analysis · 10 analyses per month · Photos never kept on our servers
Local-first by design. Not by option.
Most fitness apps send everything to the cloud. We did the opposite: Body Tracker has no account, no server for the tracking, no ad tracker. Your photos, weight and measurements stay on your phone, protected by its encryption, in a space separate from your gallery. It isn’t a setting to switch on — it’s how the app is built. We treat body photos as sensitive data (GDPR article 9), and our business model is the subscription — not your data.

“Visual review” is not a medical device and does not replace a healthcare professional’s advice.
The questions people ask before downloading.
Are my photos sent anywhere?
No. Photo, weight and measurement tracking is 100% local: everything stays in a database on your phone, protected by device encryption. The only exception is the premium “Visual review” feature: when you tap “Analyze”, the chosen photo is sent to generate the analysis, then our server does not keep it. Nothing is ever sent automatically.
Do I need to create an account?
No. Body Tracker works without an account and without a connection. You open the app and get started; your data is tied to no online profile.
What exactly is “Visual review”?
It’s the AI analysis of one of your photos: a body composition estimate given as a range (e.g. “~18–23%”, never a single figure), posture observations and two or three generic tips. It can also describe the change between two photos. It’s a visual estimate, not a measurement, and it’s not medical advice.
Is the analysis reliable?
It’s a visual estimate, to be taken as a marker, not a clinical measurement. Body composition is always given as a range, with a margin of a few points shown on screen. The tool makes no diagnosis and assigns no score.
Are my photos used to train an AI?
No. Photos sent to “Visual review” are never used to train a model, and the analysis creates no biometric identifier — it only estimates composition and posture. Details are in our privacy policy.
Which platforms is it available on?
Body Tracker is available on iOS and Android — you can download it right now from the App Store or Google Play.
How much does it cost?
The full tracking — photos, comparison, weight, measurements, reminders — is free. Only the “Visual review” analysis requires a premium subscription. The subscription costs €5.99 per month or €39.99 per year; the App Store and Google Play show the exact amount in your currency.
