TrendCentral: Possibly the most gentle alarm clock on the market, this bio alarm clock app
uses your iPhone’s accelerometer to monitor your sleep patterns. By
simply placing your iPhone under your bottom sheet, the Sleep Cycle
alarm clock monitors when you’re in your lightest sleep phase, thus
making waking up less like a clonk on the head and more like rising
after a long, restful nap. It costs just 99 cents, but the prospect of
not having to pound the snooze button for an hour every morning seems
priceless to us.
