As of now, it dosen't solve word problems, which I hope will be an added feature in the nearest future. This app has been super helpful and the way it explains how to do problems is simple and really easy to follow and understand, since it can be used offline, it is super convenient.
It's great! It doesn't just give you the answer, but it shows step-by-step what to do! And though it's basically getting the answer with the click of a button, it still teaches the user how to do it! There's an infinitesimal amount of reasons why I wouldn't use this app if I'm having trouble with a problem! ^w^.
