I sleep poorly. In fact, insomnia has plagued me for years. As it turns out, even when I think I'm sleeping well, I'm usually not. There's nothing worse than a shoddy night's sleep followed by an abrupt alarm going off when you've finally settled into a deep slumber.

Enter: Sleep as Android.

By using the accelerometer in your phone, Sleep as Android not only tracks how restful your sleep was during the night, but it also determines the best moment to wake you up. Rather than setting an exact time to wake up, you enter a "time range" in which you'd like to be woken. Sleep as Android looks for a time during that range where you're sleeping lightly (or not at all) and goes off. More times than not, it means waking up feeling refreshed, as opposed to my normal routine: groggy and coffee-starved. If you have trouble sleeping, or just prefer to wake up feeling refreshed, give Sleep as Android a try. It's free for two weeks, then only $2.99 if you want to keep it. I've listed only some of the features here, but check it out, it's truly an awesome program: https://sites.google.com/site/sleepasandroid/home.
