BodyClock, the alarm that starts from your sleep cycles
Set bedtime or wake time: the other recalculates in 90-minute cycles. Reminders, alarm and widget — no ads, no account.
Here's the solution
A sleep cycle lasts 90 minutes. The last time you edit stays the anchor; the other follows. The free edition covers one rhythm for every day. Pro unlocks a rhythm and colour per day, more reminders, the full alarm and a local backup. Everything stays on the device; the Pro purchase goes only through Google Play.
