If two iPhone alarm failures in less than three months (the Daylight Savings bug and the New Year’s bug) isn’t motivation to grab a 3rd party alarm app, we don’t know what is. Check out these feature-packed replacements for dependable time keeping.

Apple’s had some real trouble with the default iOS alarm clock over the last quarter. In November a bug with DST caused a significant number of alarm clocks to go off an hour late and then an equally significant number of alarm clocks failed to go off in the New Year. Although the alarm clock app was supposed to resume normal functioning by January 3rd it has failed to do so for many people. In light of all that, it’s pretty obvious you can’t trust your iPhone’s alarm clock application. We’ve rounded up some feature-packed alternatives to help you hit the ground running (and on time).

Alarm Clock + (Free)

Alarm Clock + sports a high visibility display coupled with weather updates. Behind the scenes you can adjust the brightness, set your alarm to a music playlist, adjust the alarm volume, and customize your schedule with multiple alarms (one set for the weekdays and one for the weekends, for example). Alarm Clock + also has a handy flashlight function. Pull your device off the dock and give it a shake to turn on the flashlight—perfect for late night trips to the kitchen or bathroom.

Alarm Clock Pro ($0.99)

If you’re longing for a traditional digital display with some bells and whistles under the hood, Alarm Clock Pro is a perfect match. When your phone is in landscape mode it looks just like an old-school alarm clock but sports lots of extra useful information like the current weather and day of the week. It comes with 11 built in alarm sounds or you can use a custom playlist. As of iOS 4 the alarm works even if you forget to turn the app on and like previously mentioned Alarm Clock + it has a shake-for-flashlight mode. [View Alarm Clock Pro in the App Store]

Sleep Cycle (Free)

If Alarm Clock Pro sticks to the traditional alarm clock format then Sleep Cycle deviates wildly. Instead of blaring out a traditional alarm at the exact moment you’ve set it for (say, 6:30 AM) Sleep Cycle uses the sensors in the iPhone to monitor your sleep patterns and wake you up when you’ll feel most refreshed. For example, if you set the alarm for 7:00AM but your movement indicates that waking you up gently at 6:40 would be best then Sleep Cycle will do so. Sleep Cycle rouses you when you’re in a lighter sleep state, a much gentler way to ease yourself out of bed. [View Sleep Cycle in the App Store]
