This Is a great app for quick answers and solutions but the time and effort used to press and exit out of places is a bit long as I have to go out change language and after 1 take I have to do it again, but if you are looking for a good and easy way for kids to learns it's very helpful, but to improve I wish they had a button that would allow to expand answer cause some of the questions are only given answers and not a working out solutions. but this app is AMAZING!!!!! 👏 👏 👏 👏

This app is the best app I have ever downloaded! It litterly writes the problem down, solves it, and shows it's work!!! I got a F- in math, so I started searching for any apps to help me out with math. Then I came across this app and it brought my math grade up to an A+! This app did way more than I expected! It's amazing! I definitely recommend!! 5 stars! Please download if you need help with your homework or don't know how to do a problem! All you have to do is copy it down!

This has got to be the absolute best free ai assist app. It's not just for math. I used it for legal assistance, & it has the most thorough results immediately. It's priceless, & I hope by saying this that I'm not cursing the "free" part. I'll pay for the upgraded tools when school starts as I can't imagine what more this already miraculous free app can do. I thank the creators of this app for thinking of the folks who can only afford free apps. It helps & leaves room to still think & learn.
