Other than that, perfect app, it has a little bit of difficulty trying to work on certain ones but hey, its the best app out there. And best of all I'm learning how to do it so I'm not just copying answers. It shows full steps with explanation from expert answers including mathematical books. I'd say it's still very useful and gives all options you could need.
To much of a good thang is bad though just don't cheat on you're test/quiz with it just probably use it for studyingand expecially don't use it on you're final exams or big tests.
Only thing wrong (prolly just bc my phone is stupid) is that the photo mode always moves in the final image, so I have to like, take a picture of the space underneath of what I want, which uuh, makes no sense but whatever, I can type too. I know they have to make money some how but I'm broke.
