Alarm Clock: Alarm Clock Xtreme

This app forces you to do some maths and easily puts the stock Android alarm clock to shame. While Maths is surely not the most palatable way to start the day, but it does promises to make you more alart than my previous alarm clock.


Mathematical teasers pop up on the home screen at the time your alarm has been set. The app offers five levels of difficulty – easiest to hardest. There are two versions of the alarm clock:

  • Free – ad supported
  • Paid – No ads
