Smart alarm clock for mobile phones

HappyWakeUp ArousalClock is a smart alarm clock for your mobile phone. The alarm time is set normally with the mobile phone. You put your phone beneath the pillow or the bed linen or near you while you sleep. It then actively monitors your sleep using the microphone of the mobile phone by listening to your movements in bed. It then looks for the appropriate almost-awake moments. During the last 20 minutes before the ultimate alarm time, the analysis is activated to give a soft alarm signal, if there are movements indicating that the you are awake or "almost awake". If you are sleeping calmly, no alarm signal is given before the ultimate alarm time.
