Play Numbs, a number app for iPhone and iPad.

NUMBS

When it comes to compatibility, your new number app, Numbs, should not worry you, as apart from your iPhone, it will also fit perfectly on your iPad and even your iPod touch. The game has been optimized for touch devices and it will hence work perfectly on most iOS devices, including the brand new iPhone 5s and 5c. However, to ensure that your Numbs experience is optimal, do check that your smart devices are all running on iOS 6.0 or latest. However, playing on an iPad or an iPhone makes no difference with this mind testing game and this is simply because screen size would make little difference to the actual game. Numbs is visually awesome on whatever device you choose to run it!
