App Review: Sleep Cycle Alarm Clock
If you find yourself waking up groggy to your alarm each morning, Sleep Cycle is the perfect solution. By analyzing your sleep, Sleep Cycle intelligently wakes you when you’re in your lightest sleep phase. What are sleep phases? Sleep Cycle explains:
“While you sleep, you go through a cycle of sleep phases. The first phase is light sleep, followed by deep sleep and a dream state referred to as REM-sleep. A full sleep cycle lasts about 90 minutes and is normally repeated several times each night.”
