iPhone alarm is a joke
1. While you are on a call it will ring like hell in your ear
2. While you have an active screen (email, games, etc) the alarm will popup like a notification and if you slide up (the same thing you do with a notification it will snooze)
3. No volume alarm control
4. For edit you have to tap edit (in older version you could just tap the alarm)
I could go on and on...
