Use it or lose it
AI does more of the thinking. Your brain still needs the practice.
Every task you hand off to a calculator, an autocomplete, or an
assistant is a rep your brain stops getting. The skills fade
quietly — and the only way to keep them is to keep using them.
BrainGym is eight short drills built for exactly that: math facts,
working memory, attention, estimation, reading recall, task-switching,
and inhibitory control.
Try an exercise
How it works
One skill, one drill
Each exercise trains exactly one thing — a math fact, a running
total, a sequence of squares — so there is never any doubt about
what got better.
Ranks, not scores
Most exercises use a simple rank ladder that moves with real
performance, not time spent. Get sharper, rank up.
Nothing is collected
No analytics, no tracking, no learner accounts, and no
leaderboards or streaks designed to pull a child back. If you
sign in, the account belongs to you, the adult.
How an exercise is built
Feedback, not lectures
A tight, focused drill for one skill, not a lesson to read.
Every attempt gets instant feedback, right away.
Runs as one page
Every exercise is a single page with its own styling built in — no
separate app, no install, nothing extra to download.
No artificial pressure
No timer pressure beyond what the drill itself needs, and no way
to fail permanently — get one wrong and you rank back down a
notch, not out.
