How it works · 3 steps

From your plate to your patterns.

Bring your meal log and wearable readings into the same history. KeepEatClean helps you explore which eating habits suit you, through patterns that hold up in your own data.

Step one

Build the food history

Log your usual meals and meal times by photo, barcode or search. Review each estimate and edit the food or portion when needed, so the record reflects what you actually ate.

Diary · Example day2,150 kcal
07:12Greek yogurt, berries320
12:40Chicken bowl640
15:30Apple, almonds210
21:48 Pasta, red wine Portion edited 1.5× 980

Step two

Connect your readings

Apple Watch data comes through Apple Health. WHOOP has its own read-only connection that never writes to your account. Which sleep, HRV and recovery measures you get depends on your device and permissions.

Step three

Explore patterns that hold up

Food × Body looks at usable paired days and runs evidence checks before it shows anything. A pattern helps you choose a question to explore. It does not establish cause or prescribe a diet.

Room for uncertainty

“Still learning” is a useful answer.

Consistent logging creates more history to work with. Not enough data and no clear signal are legitimate states, and the app tells you which one you’re in.

There is no guaranteed insight date and no promised improvement in sleep or recovery. Findings are associations, not proof, and not medical advice.
