Reflexy: Reaction & Focus

Wait for the signal. Take five valid attempts. See one clear median.

Reflexy gives you a repeatable software reaction test and a separate lab for short practice sessions. Your results stay meaningful because different modes keep their own scores.

A clear reaction baseline
- Five valid attempts, individual times and a median in milliseconds.
- Optional warm-up that stays outside your recorded score.
- Early taps, interruptions and invalid attempts are shown honestly.

Four different practice challenges
- Choice: respond to the correct cue; median milliseconds across correct responses.
- Go/No-Go: choose when to act and when to hold; correct decisions as a percentage.
- Targets: count successful hits in a 15-second exercise.
- Tracking: see the percentage of a 20-second exercise spent on target.

Your history, in context
Filter results by mode. Compare compatible sessions with matching units, protocol and local context. Older or imported records keep their origin instead of becoming a new-device benchmark. Export or import your saved history with validation.

Share a phone, compare a session
A local two-player comparison uses the same classic protocol. There is no online leaderboard submission or universal percentile.

Make it comfortable
Choose light or dark theme, sound, vibration and reduced motion. The app interface supports 20 languages. A translated store listing does not add further interface languages.

Know what the number means
Timing uses a software presentation/input reference. Display and input hardware affect results; Reflexy does not measure physical photon latency, remove device latency, calculate brain age or provide a medical assessment. Use consistent conditions when comparing your own sessions.
