So the retention is great, an app with excellent concept. It's a very useful app. It's a life saver i never really understood math so i couldn't help my kids but then i got this and now it helps me understand the problem and I can help them. This app is really helpfull when i need to solve a math problem, the app gives the answer aswell as it shows and explains the full way of solving the problems.

I use it ALL THE TIME to especially check my math hw, i hope the developers will do fix it. It has been improved so much, great! It does algebra now, sorry but its true, its camera detects ecuations and copies them pretty well and in case it misses a number you can simply add it.

Of course it comes with a price and a subscription, this app was really helpful I love it if there were more than five star I will give it all thanks for making this app. This is the best educating app it has helped me a lot in my studies so thank u developers.
