At least on my INC, it's a complete piece of crap. It works about 90% of the time which effectively makes it totally worthless. I can delete the alarm and add a new one and it will work for a day or so, but then it decides to not work anymore. What's more, if I set it to go off a minute from *now*, it works every time. Really pissing me off. I guess I'm going to try this ((Gentle Alarm)) app, but such a basic function needs to work 100% of the time.
