Brainy — 3 minutes a day. A sharper mind.

Brainy is a calm, friendly brain-training habit. Five quick games, about three minutes, once a day. Build a streak, keep your mind sharp — no accounts, no sign-in, and nothing to set up.

The five games

• Mental Math — quick calculations to warm up.
• Number Memory — hold a number in mind, then type it back.
• Stroop Test — tap the ink color, not the word. Trickier than it sounds!
• Sequence Memory — watch the pattern light up, then repeat it.
• Reaction — tap the instant the panel turns green.

How it works

1. Open Brainy once a day and tap Start Today’s Workout.
2. Play all five games (about three minutes).
3. See your score, and your streak grows by one.
4. Come back tomorrow to keep the streak alive.

Each game gently adapts to your performance, so it stays challenging without becoming stressful.

Frequently Asked Questions

Is Brainy free? Yes. Brainy is completely free, with no in-app purchases. Ads keep it that way — a small banner at the bottom of some screens, and one full-screen ad after your daily workout, at most once a day. Full-screen ads never interrupt a game, and the Reaction game has no ads at all.

Do I need an account? No. There is no sign-in and no account. Just open the app and play.

Does Brainy work offline? Yes. The games, your history, and your streak all work fully offline. The only thing that needs a connection is loading ads — without one, you simply see no ads.

What data does Brainy collect? We collect nothing. Your history and settings are stored only on your device and are never sent to us. Ads are served by Google AdMob, which does collect limited data for advertising — and you can decline tracking so ads become non-personalized. See our Privacy Policy for details.
