About this app
Editor Reviews
How Old Is Your Brain? is a small trivia app from KDR Games that turns the idea of a mental age into a quick party quiz. The developer is upfront that it exists purely for entertainment and that the result comes from a simple numerical formula, not any kind of assessment.
There are nine separate quizzes to choose from. Each one asks ten questions, and when they are answered the app announces a brain age. Because the quizzes are short, a full round takes only a few minutes, and the developer suggests playing alongside friends to compare results. Beyond picking a quiz and answering, the description names no other features: no training programme, progress tracking or detailed breakdown of the score.
For a modest app the reception is good. It averages 4.1 from 860 ratings, with 58% at five stars and 12% at one star. It has 50,000+ installs. The app is free with ads and has no in-app purchases. The last update was on 2025-09-19, roughly a year ago, it needs Android 6.0 or newer, and it is rated Everyone. We list one version, 7.1.0.
It fits groups of friends looking for a light laugh, or anyone who wants a throwaway quiz with a silly number at the end. People hoping for meaningful cognitive feedback should look elsewhere, as the developer itself makes clear.
