This is a recurring hourly (or minutely) chime/reminder application. Great for time management (such as for the Pomodoro Technique), meditation, cooking, timing experiments, or even as a pills reminder. Just set the time range and how often you want the alarm to go off and lean back and wait (or work, you know, be productive and whatnot). You can create multiple chimes for different needs, each with its own custom settings.
The premium key removes ads and enabled cloud sync.
There seems to be a problem on Google's end with their advertisements that causes apps to crash. They have fixed it and the update should be rolling out to users soon (see https://groups.google.com/forum/#!topic/google-admob-ads-sdk/DkjtCx_Zvn8 for more details).
