Stress & recovery
A stress score as accurate as the watches that cost $300.
We read raw beat-to-beat intervals from your Apple Watch, compute true RMSSD, and compare it to your personal sleep baseline — the same method elite wearables use. No guesswork, just your real autonomic state.
TODAY'S STRESS
From midnight to now
Scrub your whole day — see sleep, workouts and stress spikes on one timeline.
