This app is amazing! I had some problems with the camera, but then I found out it was my fault because it wasn't in the right angle. It's essentially a pocket tutor, how much better does it get?, i just tried it to see how good it was, this is the best app on google play store. THIS APP IS AWESOME it helps me so much and always give me the right answers and the way to solve them by far best math app out there especially better than photomath in my personal opinion.
