Your data, explained against your own history.
An iPhone app that brings together the health and training data you already collect and shows what it means for you: readiness, sleep and effort, compared with your own baseline, not someone else’s.
Coming soon · iPhone · United States
What it does
Insights from your own data.
Sleep, heart rate variability, resting heart rate, workouts and more, measured against your own history. Every insight shows the evidence behind it.
An AI that explains, and checks its numbers.
Ask questions about your own data in plain language. Every number in an answer is checked against your data before you see it. Cloud AI is optional and off until you switch it on.
Your devices in one place.
Apple Health, plus direct connections to Garmin, WHOOP, Polar, Oura and Fitbit.
Private crews.
Share what you choose with up to 8 friends. No public profiles, no leaderboards.
