Amazing app for math lovers

Finally
I know I'm going to be using this a lot in the upcoming school year, thanks!
Works like a charm
Does what it should. Could look a bit better
Great practice
UI could make it simpler/faster to get a new question. Other than that I didn't encounter any problems with a wrong answer being marked right. I'm definitely going to use this for test prep
