Body Tracker

A private diary for the way your body changes over time. Progress photos from the same four angles, alongside your weight — and nothing ever leaves your phone.

The new entry screen, showing a ring split into front, left, back and right.
Four angles, one continuous turn
A weight chart over three months with latest, change, lowest and highest.
Weight over months, not days
The diary, grouped by month, each entry showing weight and change.
Every entry, kept together

It stays on your phone. All of it.

There are no accounts, no servers and no analytics. Body Tracker contains no networking code at all — your photos and your weights cannot be sent anywhere, because there is nowhere for them to go. Your diary lives in the app's own private folder and is included in your encrypted device backup.

Framed the same way, every time

A guide to stand against

A framing overlay marks where your head and feet should sit, with a centre line to line yourself up on.

A ghost of your last shot

Your previous photo fades over the viewfinder so you can match your position exactly.

A self-timer

Three, five or ten seconds to put the phone down and get into place.

See the change

Progress collage

Then next to now — one angle across the months, ready to share.

Time-lapse

Your whole diary as a short video, in square, portrait or story shape.

Weight, your way

Kilograms, pounds, or stones and pounds. Reads from and writes back to Apple Health, and only ever touches body weight.

Support

Something not working, or a question about the app? Email app@j2industries.com and you will get a reply from a person.

It helps to say which iPhone you are on and which version of iOS, and — if something looks wrong on screen — to attach a screenshot.

Made to be calm

The background moves through sunrise, morning, daytime, golden hour and night as the day goes on. Nothing flashes, nothing congratulates you, and nothing compares you to anybody else.

Body Tracker is a record-keeping tool, not medical advice, and it is not built for rapid weight loss. Progress over months is the point. If tracking your body is causing you distress, please speak to your doctor or another qualified professional.
