The Reaction section is Cabe’s speed gym: 21 short games that measure how quickly you notice a signal and respond. It covers simple reactions to colour, sound and vibration, choice reactions, precise timing and arcade games where you decide on the fly.
Trains split-second timing and patience: each throw has to hit a window that keeps moving as the target changes direction.
How to play: Tap the screen or button to throw darts at the rotating target. Land the required number without hitting darts already on the target. A collision ends the round. Settings: rotation speed, dart count, and random smooth direction changes. Your score is the percentage of darts landed.
Two-step aiming, vertical then horizontal, builds movement precision and the ability to stop exactly on target.
How to play: First, aim vertically (up‑down) and press "Stop". Then aim horizontally (left‑right) and press "Stop" again. At the end you will see hit accuracy in percent.
You decide in an instant whether to be the ring or the ball. Trains fast switching and reactions to falling objects.
How to play: Hold your finger to turn the basket into a ball. The ball must pass through the basket, and the basket through the ball. If same objects collide — you lose! Speed increases over time.
A race-style start: hold the brake and do not jump the signal. Measures simple reaction time and trains false-start control.
How to play: Press and hold the brake pedal. Three green lights turn on one by one, then at a random moment a red light appears — release as fast as possible. The reaction time is measured from red to release.
Learn more →Catching moving targets trains eye–hand coordination and accurate taps at speed.
How to play: Flies are flying around the screen. Tap on them to catch. Settings: speed and fly count.
Copying gestures from the screen warms up coordination and gets you moving for a minute.
How to play: Repeat the hand movements shown on the screen as quickly and accurately as you can.
The dot appears anywhere on the screen, training how fast your eyes find a target and how accurately you tap it.
How to play: A dot appears in a random place on screen. Tap it as fast as possible. Reaction speed is measured.
You first have to work out what beats the sign, then tap. Choice reaction time under time pressure.
How to play: You play against the computer. Rules: rock beats scissors, scissors beat paper, paper beats rock. Tap the option that beats the shown one at the top. The faster your reaction, the better.
Your eyes stay on the centre while you judge the numbers at the sides. Builds peripheral vision and a wider field of attention.
How to play: Focus on the red dot in the center. Numbers appear left and right — tap the larger one as fast as possible. Reaction time is measured.
Learn more →Stop as close to zero as possible without going below it — a workout for your internal clock and restraint.
How to play: Countdown from 5 seconds starts. Tap the button as close to zero as possible. If the timer goes below zero, you lose.
How many taps can you fit into 10 seconds? A simple test of finger speed and stamina.
How to play: Press "Start" and click as many times as possible in 10 seconds. The winner is the one who clicks the most.
Catch the exact moment the fast-changing emoji matches the target. Trains selective attention and timing.
How to play: Target emoji is shown at the top. Emojis change quickly below. Press “Pause” exactly when it matches.
Stop the stopwatch on a given mark — practice for precise time perception.
How to play: You are given a random time. The stopwatch will start, and you need to stop it as close as possible to the target time.
The classic simple visual reaction test: the screen changes colour, you tap. Shows your reaction time in milliseconds and your progress.
How to play: A color appears on the screen. Tap it as fast as possible. Your reaction speed is measured.
Try it online →You press the opposite colour while the time limit shrinks every round. Trains suppressing the automatic response.
How to play: A circle lights up at the top. If it is red — press green, if green — press red. Every round you clear is worth 1 point — pressing faster adds nothing to the score. What it buys you is the next round: each one has its own time limit, 900 ms for the first and 20 ms less for every next one (880, 860 and so on, down to 20 ms in the last rounds). The limit is shown at the bottom of the screen. The timer reaching the limit, or a wrong button, ends the game.
Learn more →Reaction to a sound cue. Lets you compare auditory and visual reaction times and practise readiness for a sudden signal.
How to play: Wait for a random sound signal and tap the screen as fast as possible!
Learn more →Reaction to the phone vibrating — a tactile cue with nothing on screen. You can even train with your eyes closed.
How to play: Hold your phone. Tap the screen as fast as possible as soon as you feel a vibration!
Pick the next leaf on the left or right for 30 seconds: fast decisions with as few mistakes as possible.
How to play: Leaves grow on the vine to the left and right. Tap the next leaf above to leap onto it. Climb as high as you can in 30 seconds. A wrong tap costs time.
Catch the blue lines and dodge the red ones: attention to the right signal while steering at the same time.
How to play: Catch only blue lines in the basket. Avoid red lines! If you miss a blue line, you lose. Move the basket left-right to catch blue lines.
Chop the tree without getting hit by a branch while time drains. An arcade drill for decision speed, with Game Center leaderboards on iOS.
How to play: Chop the tree by tapping the left or right half of the screen. The lumberjack moves to that side — do not stand under a falling branch. The time bar drains: every chop refills it.
An object flies in from one of four sides and you dodge across its path. Reaction speed plus a quick spatial decision.
How to play: Your character stands in the middle of the arena. An object suddenly flies in from one of the four sides — swipe across its path. Coming from the left or right, dodge up or down; coming from the top or bottom, dodge left or right. Swiping into the object or along its path counts as a hit. Settings: attempts, speed and difficulty.
Reaction time is the gap between a signal appearing and your response. Several steps add up inside it: your eye or ear registers the stimulus, your brain recognises it, makes a decision and sends a command to your muscles. That is why reaction time depends not only on “fast nerves” but also on attention, readiness and how familiar the task is.
Psychologists distinguish simple reaction time (one signal, one response, as in Color Reaction) from choice reaction time (you have to work out which response is right, as in Rock-Paper-Scissors or Reverse). Choice reactions are always slower: the more options there are, the longer the decision takes — a pattern known as Hick’s law.
In healthy adults, simple reaction time to a visual signal usually falls somewhere around 200–300 milliseconds, and reactions to sound are on average a few dozen milliseconds faster. Online tests on a phone show slightly higher numbers because screen and touch-sensor latency are added to your own reaction. So compare yourself with yourself, on the same device.
A benchmark from sport: in athletics, a start less than 0.1 seconds after the gun counts as a false start, because no human can react that fast — the sprinter must have anticipated the signal. Read more about norms and the factors that slow you down in our guide How to improve your reaction time.
Five minutes a day is enough. Start with a simple reaction game to warm up, then play one choice or impulse-control game, and finish with an arcade game. The app saves every attempt, and the statistics show how your average and best times change.
Cabe also has a starting test: you take it once, the app stores your first result and suggests a goal for the month. After a month of practice, repeat the test — an honest way to see your progress.
Train at the same time of day and in similar conditions. Reactions get noticeably worse after a sleepless night, when you are tired and after alcohol — don’t compare those days with normal ones.
Driving, team sports and esports, table tennis and boxing, and jobs where you need to spot anomalies on a screen. But the main benefit is not the milliseconds you win — it is attentiveness. Reaction games teach you to be present, which is exactly what is missing after an hour of endless scrolling.
Yes. On trained tasks, reaction time usually drops thanks to familiarity with the signal, better focus and fewer false starts. The fastest changes show up in the first weeks of regular practice. Age-related slowing cannot be fully reversed, but sleep, exercise and attention training help you stay sharp.
Five to ten minutes a day is enough. Short regular sessions beat rare long ones: the brain consolidates a skill better when practice is spread over time.
The touchscreen, the display refresh rate and touch processing add latency. Compare results on the same device and focus on the trend rather than the absolute numbers.
