I was looking for a new math game that would be challenging and this is right up my alley! I just wish there was a more fun way of playing with the app. Kind of annoying that I can only do 5 problems then have to go back to the home screen to reselect my options to play another round. Trach definitely needs to make a game out of this, it’s too fun!

Thank you so much for creating this. The tutorial sections are clear, concise, and intuitive. The testing section is wonderful for practicing what you have learned. I wanted to let you know how impressed I was by the first few iterations you have released. Great work so far. I really hope you decide to continue working on this. You might just be training the next Euler!

There’s no unnecessary added “features.” It’s just what you need. Nothing more. Nothing less.

This app is well made. However, it doesn’t give enough information. How do I multiple by 3 digit 11’s and turn it into a 4 digit number? Not sure!
