Wake up Alarm Clocks

Alarm clocks that will get you up in the morning.

A typical night's sleep consists of different sleep phases. Sleep cycles from light to deep sleep several times in a night. Deep sleep is essential for feeling refreshed in the morning, but waking up in the middle of a deep sleep phase feels horrible. It can also leave you tired for the morning.

Sleep cycle alarm clocks try to sense when you are sleeping lightly for a easier wake up. This is usually done by motion sensors. When sleeping lightly your body will move around. This can be detected by the sensors and the alarm clock will go off if it's nearly your waking up time.

Sleep Cycle alarm clock for the iPhone will do exactly this by utilizing the iPhone's accelerometer. The alarm has a 30 minute alarm window during which it will try to wake you up from light sleep.

For $0,99 the Sleep Cycle alarm clock is a bargain. What's sad is that it cannot be used with an iPod Touch. Also, the iPhone should be connected to a charger during the night.
