Not Reliable
I downloaded the Wave Alarm Clock for free. The layout looks cool and the dim swipe feature is nice. However, the adds at the bottom were so bright that it really was annoying in the dark. So, I paid $1.99 to get the full version. When setting the alarm there is a notice that reads that the alarm must be in the fog round to function. Sometime during the night I got a notification and the alarm clock ended up going to the background. As a result the alarm did not go off in the morning and I was late to work. This is more of a toy than a reliable alarm clock.
