Mi Challenge Alarm is a uniquely designed alarm clock for your Windows Phone that hopes to make it difficult to constantly hit the snooze button or to sleep through your alarm. Being a challenge alarm, Mi will present you with a series of questions based off your music and image files. If you fail to answer one of the questions, the alarm will resume its annoying clammer.
Mi Challenge Alarm has a bit of appeal and is a nice addition to the growing alternatives to the native Windows Phone alarm. However, it is a little dependent on your music and photo libraries having plenty of material to choose from.
