The idea
Most sleep advice is generic ("8 hours!"). RISE tracks your actual sleep debt — the cumulative difference between the sleep you need and the sleep you get — and schedules your day around your energy peaks.
What we noticed
- Week 1: uncomfortable truths about your sleep debt
- Week 2: the wake-time suggestions start making sense
- Week 3-4: consistent energy improvements, especially afternoon
Honest limits
- Subscription after the 7-day trial (~$35-70/year)
- Works best with consistent schedules
- It guides — it can't make you go to bed
Bottom line
The most evidence-based sleep app we've tested. If sleep is a problem, start here.
