2) I Can’t Wake Up!

If you want a choice of different ways to try and get yourself out of bed, then Can’t Wake Up! delivers a variety of mini games: From memory to writing to math, you can pick your puzzle, which must be successfully completed before the alarm sounds can be silenced.
What we also like about this app is the options you’ve got for tracking how well you’ve done in terms of getting out of bed when you should be. You can use the app and all its features free of charge, though an in-app purchase is available to remove the adverts.
