Quick Brain

Fast-paced mental-maths training with daily challenges.

iOS · Android 10M+ downloads

Quick Brain was the first app we released, back in 2016. It’s a short-session mental-maths trainer: you pick a category, you have a minute or two, and you solve as many problems as you can.

The app is designed for the in-between moments — waiting for coffee, commuting, a short break — rather than long sessions.
