11 quick brain games, daily streaks and a personal Mind Profile. A few focused minutes a day to sharpen your reaction, memory and focus — no sign-up needed.
Reaction is a brain-training app built on one simple idea: a few focused minutes a day make your mind faster and sharper.
11 quick games, each under a minute:
• Reaction — tap the instant the screen turns green
• Aim — pop targets as fast as you can
• Memory — repeat a growing pattern
• Focus — name the ink colour, ignore the word
• Digit Span — memorise and recall number sequences
• Tracking — keep your finger on a moving target
• Quick Math — solve as many problems as you can in 30s
• N-Back — the classic working-memory challenge
• Rotation — spot the rotated shape among the mirror images
• Schulte — find 1 to 32 in order, against the clock
• More or Less — snap-judge which side has more
Build a daily habit:
• Daily Challenge — a new game picked for you every day
• Streak — play each day to keep your streak alive, with a gentle reminder so you never miss
• Leaderboard — see where you rank worldwide with Game Center, this week and all time
• Results & Mind Profile — every score feeds a skill rating across Reaction Speed, Visual Attention, Working Memory, Processing Speed, Spatial Reasoning and Motor Control. Watch yourself improve over time.
Why you'll love it:
• Fast — sessions take seconds, perfect for a coffee break
• No account — no sign-up; your scores and streaks stay on your device
• Offline — every game works without an internet connection
• Ad-free option — remove ads forever with a single one-time purchase
Train your reaction, memory, focus and processing speed — and feel good about doing something for your mind every single day.
