This alarm clock app does more for mankind than just making sure you get to work on time: it uses your Android's idle computing power to help University of Vienna researchers analyze protein structures to help find a cure for diseases like cancer and Alzheimer's. When you set your alarm, your device receives a data packet; when the alarm goes off, it sends its completed work back. Now you can feel accomplished the moment you wake up in the morning. [Free]
