AlarmRun

AlarmRun is really effective alarm clock for one simple reason: it sends a text message to any one of your contacts if you don't wake up in time.

In the AlarmRun settings, you can choose who to send the text message to and what it says. By default, the message simply informs the receiver that you're still asleep and you need help waking up, but you can edit it to say whatever you want.

Other more extreme features in AlarmRun let you send a text message to a random contact on your list or even publish a random picture from your gallery on any social network. If you activate this option and fail to wake up in time, the app will publish any random picture on Facebook or Twitter.

AlarmRun is an effective and dangerous app. While it might give you a good incentive to wake up, you might not want to risk having certain pictures posted publicly.
