Very best app for solving math problems that I could not even understand, i see trigonometry but not geometry. On top of that it then explained how to solve it myself. This is not time consuming like other apps and the scanning feature is also fast, this app is good for both answering anything in math that is written out in numbers in seconds and explaining the steps, though it kinda sucks that a lot of stuff is locked behind a Premium subscription, and it would be nice to see a feature for picture and word problems.
