About to switch from Palm OS PDA (Th-55) to iphone and looking for replacement for an old program called Pester. I'd like the timer program to: 1. Let me choose which of at least several different sounds for when the alarm goes off. 2. Let me set a repeating alarm which will go off every X minutes where I can set X to be from 1 min to several hours. 3. It would be nice if I could have several alarms running at same time (though not totally necessary). Thanks for your time.
