I will recommend it for those are facing problem in any topic related to maths, you should definitely try this app out though it's taking money for detailed explanation now, till i found this, due to the lockdown I can't attend my tutions or school! But I need to start studying.
I had a packet like 5 pages and it was due Monday. Must have for any math student. And you can even learn while. It's been a life saver, it is pretty useful for to see your answer is correct or not, live this app will continue to use, i really prefer the new camera feature over the older one, with the old way to capture it was automatically catching whatever you were filming like when you went to your notebook and moved the phone a bit it captured a different math problem so the new way solved it but I believe adding both ways to capture and giving the user a button to switch to whatever is comfortable for him at the moment would raise positive reviews because sometimes taking a picture is consuming more time.
