I used to use step out of bed to do the same thing, but had to switch apps because the interface was so clunky. alarmys interface is way more intuitive. also, alarmy still works if my phone is set to silent.
my only complaint and the reason for 4 stars instead of 5 is that the picture alarm way too picky. it takes me at least 10 tries to dismiss the alarm.
