It also shows me the steps and a good point is that aid do not disturb while using this app, it can solve almost any math, great app, has the solution to almost any algebra problem, and I love the camera feature.
Don't know how to find the SD? No problem. Some of the solutions' are convuluted and not what the actual best way for a human to solve, but mostly it's great. Can't believe how stunned I am with the app, this app is amazingly helpful. Edit: they fixed it. Please keep updating this app it's amazing.
This is an awesome app that literally let's you take photos of a textbook or anything thing, photos come out a bit blurry, but other than that, if your having trouble scanning, I recommend turning on the flash, if your in the dark.
