SleepMaster is a sleep monitoring and wake up alarm clock application. SleepMaster records your movements during your sleep cycles and wakes you up in the lightest sleep phase. With the help of built in accelerometer SleepMaster can detect very gentle movements without false detection thanks to the sensitivity settings. You can also visualize your sleep cycles on charts and view your sleep statistics.

NEW: Integrated Sleep Relax (Sleep Timer) function with four professional atmospheres (Sea, River, Rain, City) to help you fall asleep.

Put your phone on charger, place it near to your pillow and leave the rest on SleepMaster!

    Good idea in theory but the overheating problem is definitely an issue. No other app causes my phone to heat up like this one.

    Never had any 'overheating' issues with this app. Some reason the settings no longer save but the sleeps stats do though...

    I loved this app during trial. Since buying full version my screen stays lit up all night and I can no longer use it. Very disappointing. Pls fix.

    It was cool to see a graph showing how long I slept and how many times I woke up in the night. Nice app.

    Background is not black. Could burn your screen.

    Would like the option of waking to a random song from a playlist on the phone.

    Good, but my phone feels like it's about to go on fire when I wake up and it wasn't like that before so idk if it was because of an update or something but otherwise its a great app...great job

    DO NOT DOWNLOAD THIS APP!!!!!!! it will overheat your phone. I read the reviews and thought most people were simply using wrong or had other phone issues but my phone is in great condition and got hot enough to burn my hand in just 2 hours. Horrible app. It will ruin your wp7.
