Works completely if connected – Alarm Clock HD by iLuv Review

You have to have a clock made by these people if you want the alarm to work. If you don't have the clock, just use the pre-installed alarms on the iPod or iPhone. If you do have the clock, use the handy volume control buttons on it to set the alarm volume, because the unconnected iPod defaults to medium volume if it isn't plugged into the clock, but seriously don't bother with this app if you aren't going to get the clock.
