Ah I gave up using SGS3 alarms. I found I'd miss an alarm I thought I'd set.only to find it had set itself to go off the following Tuesday (having set it on a Tuesday to go off on Wednesday). Which when u have quite a few hospital appointments like I do. Its not good, as missing an appointment can take months to get another date.
I use a free very customisable app...
Alarm Clock Plus
It is the best I've found in a while. And a nice feature I like is... a nap alarm. U press n hold and u get an increment choice... 10 / 15 / 20 / 30 / 45 etc etc!!!
