RISE, from Rise Science, deliberately skips sleep stages. It tracks two figures instead: sleep debt built up over the past fortnight and circadian rhythm, then predicts when energy peaks, when the afternoon slump lands and when melatonin should start rising. Input can come from phone use and movement, or from Apple Health, Oura and Fitbit. The app took an Apple Design Award in 2023 and costs around $69.99 a year.
The daily energy timeline earns its keep for shift workers, athletes and anyone scheduling demanding work around a schedule that moves. Habit reminders arrive at the appropriate hour rather than in a morning heap. Readers who came for REM percentages, snore audio and night by night graphs will feel short changed, and there is no permanent free tier.
