Quit relying on your tablet's stock clock to get you up in the morning. Alarm Clock Plus offers an unlimited number of alarms, with the option to do math when you awaken, or set your alarm to music, playlists or even apps such as Pandora. You can shake to snooze and tweak snooze duration. The interface is supereasy to use, and we like that you can set the alarms to gently fade in. A $0.99 premium version is also available, if you prefer to avoid ads.
