Risetime review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

Risetime is an Android alarm clock for people who want wake-up times tied to the sun rather than only to a fixed hour. Alongside fixed-time alarms, it can schedule alarms around sunrise, sunset, solar noon, nadir, or custom solar-angle, shadow-length, and day/night-fraction anchors. Users can add an offset before or after an anchor and choose recurring weekdays. This makes the app especially relevant for schedules that shift with the seasons, while people looking for sleep tracking or wake challenges should look elsewhere.

Its defining feature is the range of solar anchors and the way Risetime recalculates their times daily. Solar calculations happen on-device, and the app is described as working offline without accounts or analytics. That combination suits users who want solar-based scheduling without relying on an internet connection. Risetime also includes countdown timers with repeating cycles, so it covers basic timer needs alongside alarms. The published feature set is centered on alarms and timers, not broader sleep or wellness tools.

Risetime is free for up to three alarms and three timers. An optional supporter purchase, available yearly or as a one-time purchase, unlocks unlimited use; the published description does not state amounts. Google Play Billing is listed for purchases, and support is offered by email. Reliability checks flag phone settings that may interfere with alarms, a useful aid for a schedule that depends on alarms firing as intended. Choose Risetime if solar-event timing, offline calculation, and straightforward timers fit your needs; choose a broader alarm app if sleep tracking or wake challenges matter more.
