One coach. All your health data.

Workouts and check-ins in Oak. Nutrition, sleep, and recovery from Apple Health. Analyzed together. You already wear the device and log your food. That data should be working for you—not sitting in separate apps.

Data without interpretation is wasted effort

Apple Health collects calories, macros, sleep, HRV, resting heart rate, activity, and weight. Your training app logs sets and reps. Neither alone tells you why progress slowed last month.

Oak unifies the picture

Oak pulls health data from Apple Health and combines it with workouts and check-ins you log in the app. The AI coach identifies how nutrition, recovery, and training interact—and what to change next.

Built for data-rich athletes

If you have meaningful history in Apple Health and consistent training logs, Oak is built to finally leverage it.
