We believe everyone should have access to fun, free, and effective tools to train their brain and measure cognitive performance — no ads, no paywalls, no nonsense.
To make high-quality cognitive training accessible to everyone on the planet — one memory challenge at a time.
Built on proven psychological principles like the digit span test used in clinical assessments worldwide.
Automatically adapts to your skill level so you're always challenged at the perfect intensity.
From students preparing for exams to seniors staying sharp — memory training benefits all ages.
Most memory apps are full of ads, paywalls, or pseudoscience. We were frustrated.
We wanted a clean, beautiful, lightning-fast memory test that actually works — inspired by real cognitive science — and completely free.
So we built it. And now over 50,000 people use it every month to train their working memory and have fun doing it.
