Angle Reader
Angle Reader is our iOS version of our popular Android game, of the same name. However, iOS Angle Reader has some big advantages over its Android counterpart in that is saves scores to iCloud so your results are synced across devices! Additionally, there are more levels to make it a challenge without being impossible to progress with your naked eye.

Angle Reader is good for those learning to read angles with a protractor, or for those wishing to improve their accuracy with visually identifying angles. If you're interested, you can find more information about it on the iTunes App Store.
