Keeping Time with the Best iPhone Clock Applications

Sleep Cycle is an app that sets your alarm to wake you up according to your sleep pattern. Before going to sleep, open the application and set your alarm for the latest time you want to wake up. Once the alarm is set and the app is opened, set the phone on your bed and go to sleep. Sleep Cycle uses the accelerometer in the phone to analyze your REM stages of sleep (based on movement of the bed). When the time for your set alarm is near, the alarm will go off at the lightest stage of sleep possible (within a 30 minute window). The app claims that this technology will help you wake up feeling more rested. When you do wake up, you are provided with a graph that charts your sleep analysis.

Alarm Clock Pro is a beefed up version of Alarm Clock Free. Alarm tones can be set to songs stored in your iTunes library. Select from different clock themes as well. For only $0.99, Alarm Clock Pro is a great choice.

Another app based on sleep cycle research, Absalt EasyWakeup Classic works similar to Sleep Cycle. The app costs $9.99, more expensive than Sleep Cycle because it has more options and allows you to program your alarms for the entire week. If you want the bells and whistles, along with the option to wake up to music from your iTunes library, the $9.99 is worth it. If you only want the sleep cycle technology, you'll save quite a bit of money by going with Sleep Cycle.
