Train your reaction time, reflexes, focus and hand-eye coordination with quick exercises designed to challenge both speed and decision-making.

Reflex Training: Reaction Time combines reaction time tests, reflex games and cognitive training exercises into one daily workout. Practice for a few minutes, track your results and challenge yourself to react faster and stay focused under pressure.

REACTION TIME & REFLEX TRAINING

Test your response speed in milliseconds and train different types of reactions instead of repeating the same basic tap test.

• Synaptic Start
Hold the screen and release as soon as the signal changes. Test your raw reaction speed and practice faster responses.

• Cognitive Chaos
Ignore distracting information and react to the correct signal. A Stroop-style focus exercise that challenges attention and quick decision-making.

• Vector Swipe
Read the direction, process the signal and swipe fast. Train reaction speed, concentration and mental processing.

• Gyro Defender
Tilt your phone to block incoming targets. Practice hand-eye coordination, spatial awareness and physical response speed using your device's motion sensors.

• Spatial Grid
Find and hit targets across a changing grid. Challenge peripheral vision, visual scanning, target acquisition and accuracy.

• Math Reflex
Solve quick problems against the clock. Combine mental calculation with reaction speed and concentration.

DAILY REFLEX WORKOUTS

Daily Training gives you a fresh mix of exercises so you can practice consistently without deciding what to play next.

Complete short training sessions, compare your results and track your reaction time over time.

TRAIN MORE THAN REACTION SPEED

Use the exercises to challenge:

• Reaction time and response speed
• Reflexes and quick decision-making
• Hand-eye coordination
• Focus and attention
• Peripheral vision
• Visual scanning
• Spatial awareness
• Processing speed
• Accuracy under pressure

FOR GAMERS, ATHLETES & EVERYDAY TRAINING

Fast reactions matter in many situations.

Gamers can challenge their visual reaction time, decision speed, focus and coordination. Athletes can practice quick responses and spatial awareness. Or simply use the app as a fun brain training routine to test how quickly you can react.

Short sessions make it easy to train before gaming, during a break or as part of your daily routine.

TRACK YOUR PROGRESS

See how your reaction time changes as you practice.

Try to beat your previous scores, improve your consistency and discover which types of reflex challenges are your strongest.

HOW FAST ARE YOUR REFLEXES?

There's only one way to find out.
