CMath helps you to be a walking calculator. Whether you are getting prepared for your management consulting interviews, or are motivated to challenge your brain and improve your mental math skill, CMath is designed to help you do calculations faster and more accurately.

You can try the app in 3 major modes. Text2Text lets you see the question and enter the answer via keyboard. Speech2Text, you hear the question and answer to it via keyboard (it is much harder to answer when you don't see it!). And last but not least, Speech2Speech; You hear the question and answer with your voice.

Excellent for management consulting applicants

This app is what I needed to get better in math for interviews. The feature that you can hear the question instead of reading numbers is perfect. It seems like different parts of the brain get involved. Thank you.


Fun for math nerds

Frustratingly, fun agree challenging. I really like how you can play via text, speech, or a combo. The ads aren't too intrusive either, which is rare.

My only issue was that the leaderboards don't seem to be working/accessible.


Math frenzy

Very appealing app to practice your maths. I love the professional layout and the timer. Also the adaptive level based on your performance is very clever. Well done!
