Makes math fun

This app does a great job of gamifying math problems and keeping me interested in improving. My favorite time to use it is in between sets at the gym. It’s the perfect 1 minute break before you get back to work. Also kinda weird finding but the more tired I get the better I get. Best score I’ve gotten was after a heavy squat and had a head rush.

Either way great game and couldn’t think of a way to improve it

Thanks for the awesome review! We love hearing how FastMath fits into your gym routine. Maybe heavy squats are the secret to mental math mastery! 😄 Keep enjoying those head rush high scores, and if you ever have ideas or feedback, drop us a line at

If you’re struggling with your mental math, use this.

After just one week I already noticed my abilities improve. It was frustrating that I used to be really good at it, but since I’ve had little practice in recent years, my skills have diminished. This app is clear and straightforward. You can get started immediately improving your math skills. Definitley recommend!

Haja fun ,

Good app.

This is the kind of no frills app I've been looking for. I've always been kind of ashamed of my math skills. I always felt like I was struggling to keep up. I got this app to try and improve my skills and have seen some improvements since I started using it. I like not having to have my phone or a braille writer nearby just too do a simple math problem.
