Work your memory with four short training modes, then see today's brain age.

Four training modes
- Position memory: numbers appear on a grid, then you tap their spots back in order.
- Sequence memory: colored buttons flash one by one, and you repeat the pattern.
- Word memory: memorize the words you are shown, then type them in. Five categories are included: food, animals, jobs, cities and objects.
- Number memory: memorize a string of digits and enter it, forward or in reverse.

Every mode has levels, so the difficulty climbs step by step as you keep going. See how far you can get today.

Brain age
Your brain age is calculated from your average reaction speed, your average accuracy, the highest level you reached, and your run of results at 80% accuracy or better. The home screen shows today's brain age next to your real age, worked out from your birth year, so you can see the gap at a glance.

Records and habits
- Stats: total games played, average accuracy, average reaction speed, highest level reached, and a list of your recent results.
- Streak: the home screen counts how many days in a row you have trained.
- Reminder: pick a time and get a daily nudge to train.
- Theme: choose system, light or dark.
- Readability: every screen is built with large type, 16sp and up.

Privacy
Your name and birth year stay on your device and are never sent to a server. No sign in, no account, nothing to set up. The app is free.
