About

Sheep to Sleep

Features
Read full description

Sheep to Sleep turns the classic bedtime ritual of counting sheep into a quiet companion for winding down. - Sheep counted aloud for you — just listen, no need to watch the screen - A gentle breathing guide to settle down before bed - A sleep timer in the Sheep tab that stops automatically - Your past seven nights of sleep, side by side, in Progress - No account, no ads The voice keeps going when you lock the screen, and ends quietly on its own (after 100 sheep or your timer). A calm way to end the day. Reading sleep records and writing breathing sessions to Apple Health are separate optional features, both off by default. The app can read up to your past seven nights of recorded sleep for the morning card and This week's sleep. It can save completed breathing sessions as Mindful Minutes only when you enable that setting. Both are handled only on your device. Sheep, Breathing, Progress, and Settings each have their own tab. Progress also includes This week's sleep and a Tonight's Preparation checklist.
