Sleep analysis: understand duration, efficiency, deep sleep and REM
Vita (100old.app) turns the sleep data from your WHOOP or Apple Watch into analysis you can actually read and track — duration, efficiency, deep/REM structure, sleep debt and consistency, with WHOOP-style weekly trends and per-night detail.
What sleep metrics Vita shows
It's more than 'hours slept'. Vita breaks down your sleep structure so you can see whether the problem is falling asleep, too little deep sleep, or an irregular schedule.
- Duration & efficiency: time actually asleep vs time in bed
- Deep / REM split: the stages for physical repair and memory
- Sleep debt: your recent accumulated shortfall
- Consistency: how regular your sleep and wake times are
An enhancement for WHOOP users
WHOOP records your sleep; Vita helps you use it — viewing sleep alongside recovery, training and Body Age as trends, and letting the AI coach give concrete adjustments based on it. Without a WHOOP, Apple Watch sleep data supports the full analysis.

What is sleep debt?
Your recent accumulated sleep shortfall. Vita shows how much you need to make up to recover.
