SleepRoute - Scientific Alarm

Sleep Route works out when to set your alarm so it goes off at the end of a sleep cycle instead of the middle of one. WHY WAKE TIME MATTERS Sleep runs in cycles of roughly 90 minutes. In each one the brain moves from light sleep down into slow-wave sleep and back up through REM, the stage where most dreaming happens. Most people go through four to six of these cycles in a seven to nine hour night. An alarm that fires deep inside a cycle leaves you groggy, while one placed near the top of a cycle is far easier to wake from. sleepRoute does that arithmetic for you. THREE WAYS TO SET IT Sleep now — tap once and see the best wake times if you fall asleep from this moment, including a 25 minute power nap. I sleep at — enter your bedtime and get every wake time that completes a full cycle. I wake at — enter the alarm you already have and see when you should be asleep by. Each suggestion shows the total sleep length and the number of cycles, with the strongest options marked BEST, so you can pick the one that fits your morning.
