Great, very useful tool! – Math Interactive Review

$3 to unlock all premium features. That’s cheap considering what you’re getting for such a fantastic price. I can’t believe people are complaining that these guys built such a great app and dared to charge for it. Is an app useful to you? Or fun and entertaining? Then it’s worth paying for. I’m glad I discovered this app. It’s quite handy for reference. Best find of 2018 for me.
