Sleep & recovery
Sleep score, duration and efficiency, plus a recovery reading built from your HRV and resting heart rate against your own trailing baseline.
Personal health dashboard
Your whole body, on one screen.
Body Journal pulls your sleep, recovery, activity, and nutrition out of the apps and wearables you already use, and puts them in one place — with charts, history, and an AI assistant that looks for how they affect each other.
Sign in once, then connect Oura, Whoop, a smart scale, or Apple Health from inside the app.
What you get

Body & nutrition
Weight and body composition from a connected smart scale, plus a calorie tracker with a photo-based macro estimator for meals you log yourself.

What Body Journal accesses and why
Whichever provider you connect, Body Journal reads your health and fitness data — sleep, heart-rate variability, resting heart rate, steps, activity, recovery and strain, and body composition, depending on the source. If you sign in with or connect Google, that includes reading your sleep and activity data from the Google Health API.
This data is used only to build your own dashboard, charts, and history. Your recent data is also sent to Anthropic's Claude API to generate the AI insight summaries and answer the questions you ask the in-app assistant.
We don't sell your data or use it for advertising, and it's never shared with anyone beyond the source providers (to pull it) and Anthropic (to generate insights). You can disconnect any source at any time, and permanently delete your account and everything stored for you from Settings → Account. Full details in the Privacy Policy.
