Timer works exactly as advertised. Its really easy to set and has lots of nice alarm sounds. However, turning it off is a pain. I havent found a way to deactivate it. It keeps recycling and sounding alarms ad nauseum. Finally I figured out to set it to zero, and it still alarms once, but then stops. This is ridiculous for a simple timer app that will almost always need to be used once then stop. At least make a couple buttons to clearly either recycle or cancel the alarm. Ive noticed this is a common problem with most iPad/iPhone alarms.
