The Siesta Smart Alarm is an iPhone application that monitors sleep movement early in the morning and wakes you up prior to your alarm if your body is already alert. This prevents you from falling into a deeper sleep, when waking up will make you more groggy.

How it works is simple: say you normally set an alarm for 6:30 AM. Well, if you're at a certain point in your sleep cycle that is more conducive to waking up at, say 6:15 AM, maybe it's better to wake up then, instead of falling back into a deeper sleep by 6:30, when your alarm is set to blare. You'll end up waking up groggier.

Instead, we allow a window of time during which the phone will monitor your movement on the bed. Just set the phone down next to you as you sleep, place it under your pillow, or use the armband, and it will wake you up when you're transitioning between one stage of sleep and another - when your body is more suited for waking up!
