The problem
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.
In your camera roll
- Photos buried among screenshots and meal pics.
- Framing, pose and lighting that change every time.
- No clean way to compare last Monday with three months ago.
- Weight in one note, measurements in another.
- You forget to take the photo, then give up.
The result: you can’t see your progress, so you drop off.
With Body Tracker
- A dedicated space, away from your gallery and cloud backups.
- A pose guide so you frame the same way every time.
- Two dates side by side, aligned, in one tap.
- Weight and measurements attached to every shot.
- A reminder at the right pace so you never miss a take.
The result: progress becomes visible — and you keep going.
Why it works
What changes when you truly see your progress.
The visual proof that keeps you going.
The scale often lies; so does the mirror, day to day. Two photos a few weeks apart don’t. That’s what keeps the routine alive.
Intimate photos, genuinely private.
Your shots stay on your phone, in a space separate from your gallery. No account, no server, no cloud backup behind your back.
Consistency without thinking about it.
Reminders at the pace you choose — every week, every two weeks. Consistency drives progress, not a single burst of motivation.
Weight, measurements and photos, together.
Every shot carries its context: the day’s weight, waist and arm measurements. The trend reads at a glance, no spreadsheet.
Features
All the tracking. Nothing leaves the phone.
Photo, weight and measurement tracking is entirely free and works offline. “Visual review”, the AI analysis, is the only premium piece.
Guided photos
A pose and framing guide helps you stand the same way every time, for honest comparisons.
Side-by-side compare
Pick two dates: Body Tracker aligns them and shows them next to each other, or overlaid.
Weight & measurements
Log your weight, waist, hips and arms. Each value is attached to the day’s photo.
Regular reminders
Set the frequency that suits you. A quiet notification reminds you of the next photo.
Visible goal
Set a target — a deadline, a marker — and keep it in view every time you open the app.
100% offline
No connection required. Your data lives in a local database on the device, never on a server.
Premium · Visual review
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.
Range-based estimate
Body composition is given as a range (e.g. “~18–23%”), never a single figure: a visual estimate, not a measurement.
Posture observations
Shoulder and hip alignment, overall balance — plus two or three generic training and recovery tips.
Comparison between two shots
The areas where change is visible, consistency with your logged weight, factual encouragement. Always relative to yourself.
What happens to your photo
- It’s only sent the moment you tap “Analyze” — never automatically.
- Location and metadata are stripped before it leaves.
- It travels encrypted to our server, which forwards it to our AI provider to generate the analysis.
- Our server does not keep your photo. The result is stored only on your device.
- Your photo is never used to train a model and creates no biometric identifier.
Privacy
Local-first by design. Not by option.
Most fitness apps send everything to the cloud. Body Tracker does the opposite: by default, nothing leaves. It’s not a setting to switch on — it’s how the app is built.
Everything lives on the device
Photos, weight, measurements and reviews are stored in a local database (SQLite), protected by your phone’s encryption. No account, no server for the tracking.
Nothing leaves without your tap
The only data that can leave the device is a photo you choose to send to “Visual review” by tapping “Analyze”. Nothing goes out in the background.
Zero tracking, zero ads
No ad trackers, no data resale, no profiling. The business model is the subscription — not your data.
Compliant and transparent
Body photos treated as sensitive data (GDPR art. 9). Our privacy policy details every flow, in plain language.
Pricing
