Clevelevator

The average length of an elevator ride in New York City is 118 seconds. With this app, you can spend the time solving a few simple math problems!

Sadly, not all of us ride an elevator on a daily basis. Also, it will definitely not work with ALL the possible elevator vendors. If you really love math that much and, for any reason, tasks are not showing up or you're just not in the elevator, just shake the phone, you will get a task to solve. Please note that math is not an easy thing, so you should shake your phone hard enough.

As the math itself, the app is completely free! No banners. No ads.

To accomplish proper motion detection application constantly monitors sensors and as a result, it uses about 10-15% battery. Hopefully, I will improve it in future. For now, I suggest turning motion detection off when you know you will not be eager to practice some math in the nearest future. You can do it in the main application screen or from the desktop widget.

Are you a cheater? Wanna get the answers right without racking your brain? No need to disassemble the apk, you will not find the answers there. All the problems are generated procedurally. The code is available here:
