A brand new brain training application

BrainX

You already train your body to stay lean and fit. Your mind is just as trainable — and just as quick to soften without it.

The ✕ in BrainX is a multiplication sign. That's the whole idea.

Where do you actually land?

Most brain apps give you a score with no meaning. BrainX gives you a position — measured against the population, on the scale psychologists actually use.

100 — the average 115 — top 16% +15% — your goal, on your own baseline

Five disciplines

Every one adapts to you specifically — hard enough to stretch you, never so hard it stops feeling like winning.

The IQ Chamber

A full 15-minute matrix-reasoning test — 30 puzzles across six escalating rule families, not a five-question quiz. You get an IQ estimate, a percentile, and a review of every answer.

Then retake it. The goal isn't to beat other people — it's to beat your own first score by 15%. Guess your result before you start, and see how well you actually know your own head.

Who's behind this

I'm Mathias. BrainX is one of many projects I've built with AI as my co-pilot — three kids, a soft spot for small games, and a real interest in keeping my own mind sharp.

Mostly I got tired of the ads. Every decent little game turned out to be a slot machine in costume: a commercial between rounds, a nag screen where the fun should be. So I built the one I actually wanted to play. Whatever else changes here, there will never be advertising.
