I have not run into any problems at all. As a parent I want to help my kids with their homework, this app is very usefull for all students and others to under stand how to solve the quection,I think this the best app I saw the first app on maths.
It solves every maths problem, you also need to try it. This app still deserves 5 stars, helps me check my answers before submitting them so that I can make sure I have the right answer on my tests before I get a bad grade, but the problem is you just need to buy a premium or to log in there app just to know the "solution" of how did they get the answer :(.
You have no idea how many grades things has me. That's really good for maths' problems, anyways this is a great app, I was looking for something like this for a while, thanks. It helps me a lot on my math problems and if the photo doesnt work you can just type in the question, 10/10 experience, would definitly recommend with people who are struggling with some math equations.
