Where our games come from

Games you already love, rebuilt for your brain

Other apps dress up lab tasks. We start from the classics you grew up playing, keep what makes them joyful, and rebuild each one around a single cognitive skill.

Six cognitive skills

Six skills, eight games each

Every game belongs to exactly one skill, so your training stays focused and your trends stay readable. Pick a lane — or run the whole spectrum.

Honest by design

No inflated scores. No participation trophies.

Your Brain Fitness Index is one 0–100 number, benchmarked against your own age group. And until your bracket has real data, it doesn't flatter you — it says “calibrating.” We'd rather be honest than impressive.

  • Percentile bands, not vanity points
  • Graded within your age bracket — 28 isn't measured against 68
  • “Calibrating” until there's enough real data. No made-up baselines

Six short games, one from each skill, each tuned to your current rating — never too easy, never a wall. Done before your coffee cools.

The Family plan

Train together. Snoop never.

One plan, six seats — with privacy defaults built for teens.

Bands, never raw scores

Family and friends see “Above average” — never your exact numbers. Comparison without the cringe.

Consent stays with the member

Paying for a seat doesn't buy you someone's stats. Each member grants access — and can take it back anytime.

Six seats, one plan

Everyone trains on their own track, with their own adaptive ratings, streaks, and goals.
