CalcSprint

A fast mental-math game that sharpens your arithmetic under the clock

CalcSprint is a fast-paced brain-training game for mental arithmetic. Instead of typing calculations, you race to pick the correct answer from multiple choices, with the difficulty adapting to your performance.

Practice addition, subtraction, multiplication and division across Easy, Medium and Hard levels, then push further with two-step problems. A clean, distraction-free interface keeps the focus on speed and accuracy.

Real-time feedback plus streak and accuracy tracking let you watch your mental math improve over time. No account needed, and it's available on iOS, Android and the web.
