Useless
Ive seen this tech before. It seems this app is just some students demo app that hes waaay too proud of. Avoid as its a waste of time. It has a face tracker, which just puts a red box around what it thinks your face is... Period. Then there are 4 other apps which just demo that he can put a 3D model in an app and tie it to the gyroscope in your phone... Period.
Avoid.
