I have been using the free version with ads for quite a while. This one from Amazon is ad free so no more accidentally hitting some advert instead of snooze. Any different from the stock alarm clock? Maybe just a bit more extreme.
Only available for free at Amazon US.
Version 3.5.9 (latest at Google Play is 3.6.3p)
Amazon Review = 4.6/5 (734 reviews)
