What I love about this app is the innovative concept of using puzzles to wake people up more effectively. The graphics are beautiful and the alarms are soothing, so you don't feel annoyed when you wake up. To swtich the alarm off, you can choose from 5 different alarms. From a simple math quiz, shaking your phone to launch a rocket, to collecting "dragon balls" from the solar system, waking up has never been more fun!
