Coming soon to the App Store
Your weight, and everything under it
Weight, body fat, muscle, water, BMI and ten more. With a goal that tells you the date you get there, not just whether you went down.
Free, no account required, no ads.
What it does
What you use daily, and what you find out two months in.
Thirteen measurements, plus your own
Weight, BMI, body fat, muscle mass, body water, bone mass, basal metabolism, metabolic age, visceral fat, blood pressure, heart rate, glucose and blood oxygen. Measuring something else? Add it yourself.
A goal with a date
Say where you want to get and how fast, and the app tells you the day. It recalculates with every weigh-in, so you know whether you are still on time. An estimate, not medical advice.
It speaks to Health
Reads your weight and body fat from Health, and writes back what you log. If you weigh yourself on a connected scale, you type nothing. Free for everyone.
Progress photos, with the last one ghosted
The camera overlays your previous photo so you can match the pose. They stay on the phone, in the app private folder: they never reach a server.
On your wrist
An Apple Watch app with four complications for the face: weight, the week change and how far you have left. Log a weigh-in from the watch and it shows up on the phone.
Charts that say something
Your full history, and two metrics on the same chart to see whether what you are losing is fat or muscle. Export to CSV and PDF whenever you like.
How it looks
Real screenshots, untouched.

FAQ
Do I need an account?
No. You can use it as a guest and we never ask for your email. Create an account later and your data comes with you, nothing lost.
What costs money?
Nothing. The app is completely free, with no ads or subscriptions: Health sync, progress photos, full history, weekly summary, comparing two metrics and export.
Where does my data end up?
Your measurements are stored in your account so you have them on every device. Photos are not: those stay on the phone only. None of it is used for advertising or sold.
Can I delete everything?
Yes, from the app itself, under Profile. It deletes the account and what is inside. No need to write to us, no waiting.
Does it replace a doctor?
No. BodyTrack records what you measure and does arithmetic with it. It does not diagnose and gives no medical advice: for health decisions, see a professional.
