Pretty good.

Plenty of options. UI a bit awkward. RSS feed interesting idea. Screen a bit cluttered so when RSS feed or Calendar function disabled would be good to be able to move time function lower on screen. Interesting bug: when done setting alarm sometimes 1/3 of screen is cut off until you move into landscape mode. Would be better to have option to sample alarm sounds so you did not have to keep setting an alarm to hear the different sounds. ("calm alarm" is NOT calm!) Sleep sounds such as waves is a nice feature. White numbers on black background looks good. As with other clocks it would be much much better to change brightness with a finger swipe rather than having to activate a slider bar. ALSO: The screen should indicate when the next alarm is set to go off.

Whoa nelly va about Alarm Clock Rebel - Weather, iPod Music, News, Calendar, World Clocks, Sleep Sound
