Endless Treadmill is an autorunner in which you have to help a variety of different characters maintain their balance while working out on a treadmill.

As they run, you have to keep them on the green line at all times. You do this by holding your device steady and tilting it to rebalance the character when they stumble.

There are a few different characters to unlock like John, a pensioner, Alex, a music-loving teenager, and Debra, the fitness freak.

Each of them comes with their own stamina and balance stats and can be unlocked using the gold you earn while running and completing challenges.

There are plenty of challenges to take on like running a set number of meters with a character, playing a period of time without stumbling, and ranking up.

The real challenge comes from trying to beat your own - and your friend's - high scores though so you'll want to try and unlock the best characters as soon as possible.

You can also unlock new locations to work out in so there's plenty of variety in the scenery to keep you interested.

Endless Treadmill is available right now from the App Store [download] and Google Play [download].
