Sleep Phase wakeup clock

An alarm clock that monitors and analyzes your sleep cycle and wakes you up in the lightest sleep phase, making you feel rested and relaxed. This is done by utilizing your devices microphone or accelerometer to sense your subtle movements when you are asleep.

Everyone goes through a number of deep sleep and light sleep phases during the night. Depending on the phase you are in when you are woken you either feel relaxed and rested or tired. Sleep Phase wakeup clock monitors your sleep phases during a window of 30 minutes of the time of your choice and wakes you up when your sleep is the lightest, thus ensuring that you feel great every morning.

When using the microphone (available with iPhone only) to monitor your sleep rhythm, you can place your device a few meters from your bed. If background noise makes it impossible to monitor your subtle movements in bed via the microphone, or if you own an 2nd generation iPod touch, you can choose to place your iPhone next to your pillow and the accelerometer will sense your movements accurately and wake you up at the ideal phase of sleep.

Keeping your device charged during the night is recommended, as your battery might run out otherwise.

Some customer reviews from stores around the world:

- I've been trying this out for a couple of days and I am surprised how well this app works. On the first morning wake up considerably easier than it usually was, and now getting out of bed is lot easier. No need to snooze for thirty minutes or so :) I was thinking of buying one of those sunrise alarm clocks, but I am glad that I decided to try this app first!

- This app is amazing! I love it, highly recommended!

- I used it last night and I woke up really fresh and alert.

- Really helpful, way more accurate then the competition.

- Buy it!
