4) Challenges Alarm Clock

The name says it all when it comes to this particular app, which serves you a challenge of your choice to make sure you’re up and about before the alarm sound will stop. Whether it’s matching cards from memory or getting through a maze, there are lots of options.
More than most apps of this ilk, Challenges Alarm Clock manages to strike a nice balance between being both firm and gentle in terms of getting you up. You can use every part of the app without paying, but there is a premium option if you want to get rid of the ads.
