iPhone App: Sleep Cycle
Bio-alarm clock for iPhone
I’m not one to really rave on about iPhone apps – but this really got my attention. Sleep Cycle is a ‘bio-alarm clock’ now available on the iPhone.
Using the sensitive motion sensor in the iPhone it measures how deep your sleep is (e.g. deep sleep versus REM-sleep or dream-sleep). What’s more is within the half-hour window before your set alarm time, it will so that you’re in the lightest sleep – and hence feel more rested than waking from a deep sleep.
