Sleep
Sleep tracking that gets past "you slept 7 hours."
Wellness Project pulls in stage-level sleep architecture from Oura and Fitbit directly, and from Apple Watch (or any other wearable that writes to Apple Health) on iOS. We chart deep, REM, light, and awakenings against your baseline; calculate sleep debt across the week; and let Evelyn and Max read it in context with everything else.

What's inside
The sleep view a real coach would build
Total sleep + time in bed
Per-night totals plus efficiency (asleep / in-bed). Plotted across the week with your target line drawn on top.
Stage architecture
Deep, REM, light, awake — minutes per stage and percentage of total. Charted across the night and the week.
Sleep debt accounting
Rolling 7-day debt vs your target. A 7.5-hour target with a 6.5h average = 7 hours of debt by week’s end. Surfaced honestly.
Weekly architecture chart
Sleep windows visualized across the week with bedtime, waketime, and stage distribution. Drift in either direction shows up immediately.
Cross-domain insights
Late-evening HIIT compresses deep sleep. Alcohol crashes REM. Wellness Project sees the pattern and surfaces it specifically.
Multi-device source priority
When more than one device logs the same night, Wellness Project picks one source per night and dedupes the rest, so you don’t see the same sleep counted twice.
In the app
Total hours is the start, not the answer
Eight hours of badly fragmented sleep can leave you worse than seven hours of clean architecture. Wellness Project tracks both duration and quality, gives you sleep debt as a running number, and reads stage architecture across the week so you can see when something is degrading slowly.
Evelyn Cross treats sleep as the single most important longevity lever a healthy adult has. Max Kline reads it as the cleanest input to next-day HRV. Both pull from the same data layer so you never have to copy numbers between apps.
On nights with short sleep, Coach Jamie pulls back planned volume and Elias bumps tomorrow’s easy run. Same data, different uses.
