I found it impossible to wake up "on time" especially leaving home and living by myself. But this app is priced at its value as it works amazingly! It uses the iPhone accelerometer feature to monitor your sleeping patterns and waking you at the best moment. You can also see these graphs to see how well you sleep at night or if you toss and turn a lot (like me)! Great value for money app - I recommend this above any other alarm clock apps!!
