Sleep Calculator

About

Sleep Calculator REM helps you find ideal times to wake up or go to bed by aligning with 90 minute REM sleep cycles. People often feel tired not from too little sleep, but from waking during a cycle. This app solves that problem. 🌙 It offers three modes: one suggests wake times based on your bedtime, another recommends bedtimes from your wake time, and a third gives an instant calculation starting from the present moment. ✨ Key features include sleep advice tailored to your age, a visual chart of your sleep cycles, and a sleep debt tracker.
