zCube

There are two main features in this app: 1vs1 and Timer.

In 1vs1 you will be able to compete with other cubers all around the world. The best part is, you won't need a smart cube.

This feature is currently under development and will be released soon to the public.

The Timer on the other hand uses the proximity sensor to start it's countdown. You can still opt for manually starting the countdown.
