Body recomposition for Android
Lose fat.
Keep muscle.
BodyComp connects your Health Connect data with established calculation formulas: weight, body fat, calories and sleep at a glance – and recommendations where you can always see what they are based on.
- No ads
- No tracking
- Health data stays on your device
Illustrative example, not real measurements.
From scale to recommendation in three steps
No typing, no guessing: BodyComp reads what your devices already measure.
Connect
Your smart scale, fitness tracker or OHealth write to Health Connect – BodyComp reads along (only with your permission).

No black box. Just maths you can follow.
The app calculates your calorie and protein targets with fixed formulas on your device – no language model, no gut feeling.
- Basal metabolic rate
- Mifflin-St Jeor equation from age, height, weight and sex – the basis of your calorie needs.
- Protein
- Protein need per kilogram of lean mass instead of a flat figure per body weight.
- Deficit
- A moderate calorie deficit that protects muscle – capped so you do not lose weight too fast.

Frequently asked questions
What is BodyComp?
BodyComp is an Android app for body recomposition: lose fat while keeping or building muscle. It analyses your Health Connect data – such as weight, body fat, calories, activity and sleep – and derives traceable calorie and protein targets from it.
What do I need to use it?
An Android device with Health Connect (Android 9 or newer) and at least one connected data source, for example a smart scale, a fitness tracker or OHealth.
Is BodyComp available for iPhone?
Currently Android only, because the app builds on Health Connect.
How much does BodyComp cost?
Tracking, analysis and the food log are free. The AI features (coach, photo recognition, sharing workouts) are part of Premium, a subscription via Google Play that you can cancel at any time.
Where does my health data go?
Your Health Connect values stay exclusively on your device. Cloud Sync is optional and only backs up profile, food log and custom foods, pseudonymised. Details are in the privacy policy.
Does an AI calculate my calorie and protein targets?
No. These targets come from fixed, established formulas computed on your device. AI is only used for the optional coach plans and photo recognition, and only when you start them.
How do I delete my account?
On the “Delete account” page you sign in with Google and delete your Cloud Sync account together with all linked data. Local data is removed by uninstalling the app.
Ready for numbers instead of guesswork?
Download BodyComp free on Google Play and connect your scale in a few minutes.
Requires Android 9+ with Health Connect.
