Brain TrainTraining your brain shouldn't feel generic.
Eight original games, a plan that adjusts to what you're actually weak at, and a way to challenge a friend without either of you needing to be online at the same time. No account required to start — just play.
The idea
Most brain-training apps hand everyone the same lineup and call it personalized. Brain Train tracks what you're actually good at and what you're not, across memory, attention, processing speed, spatial reasoning, and mental flexibility — and builds each day's plan around the gaps, not a generic rotation. It's a short, repeatable habit: a few minutes, a visible sense of where you stand, and a plan that changes as you do. You climb by changing direction — the games rotate what they ask of you on purpose, because standing still on one skill isn't the same as getting better.

1Play a few minutes
Short sessions, eight different games, each testing a different skill.
2See where you stand
Your plan shows what's calibrated, what's improving, and what needs more reps — not just a score.
3Challenge someone
Finish a round, then send it to a friend. They play it on their own time and see how they measured up.
Eight games, eight different skills

Same shape rotated, or a mirror image?
SpeedWideye
One flash. Name the middle, then point to the edge.
Play at your own pace, or send a challenge
Every round in Brain Train is replayable on demand — which means any round you just finished can be sent to someone else exactly as you played it. No lobby, no waiting for a friend to be free at the same time: they open the link, play the same round, and see how they stack up. It's the closest thing here to playing with someone, without either of you needing to be online together.
Built to start without a commitment
No account, no email, no payment to try it. Guest players get the full daily plan from the first session — an account is there if you want your progress to follow you to a new phone, not a requirement to see whether you like it.
