Reaction Check Plus

RANJAN LTD

About this game

How fast are your reflexes? Reaction Check Plus gives you a precise, science-inspired benchmark across three dimensions of human reaction speed — and tracks your improvement over time.

MEASURE WHAT MATTERS

Most reaction-time apps flash a single color and call it done. Reaction Check Plus goes further: test your visual reflexes, your tap speed endurance, and your audio response — each with multi-attempt series so you see your true average, not just a lucky fluke.

KEY FEATURES

• Visual Reaction Test — tap the instant a color flash appears; 5-attempt series reveals your average and best attempt
• Tap Speed Burst — sustained tapping challenge that measures your clicks per second (CPS) over a timed burst
• Audio Reflex Test — react to a tone instead of a visual cue, isolating your auditory response channel
• PRO / FAST / SLOW rating badges — every result is graded against real human benchmark ranges
• Personal bests carousel — home screen always shows your all-time records for Visual, Tap, and Audio
• Stats & Analytics screen — performance trend chart plus a full scrollable log of every test you have ever taken
• Category filters — slice your history by test type (Visual / Tap Speed / Audio / Grid) with a single tap
• Haptic feedback — satisfying vibration on every tap, toggleable in settings
• Sound effects — audio cues for test start and result reveal, independently toggleable
• Tap Speed test duration control — choose your burst window (e.g. 10 seconds) to match your training goals
• One-tap clear — wipe all test history from the Data Management section when you want a fresh start
• Completely offline — no account, no internet, no data ever leaves your device

HOW IT WORKS

Open the app and choose a test mode from the home screen. The Visual Reaction test counts down, then waits a randomized interval before flashing the screen — tap the moment you see it. After 5 attempts your series result appears with a breakdown of each individual trial and a PRO/FAST/SLOW rating. Your best attempt highlights in green. Tap "TEST AGAIN" for another round or head to Stats & Analytics to see how you are trending.

The Tap Speed Burst test fills a progress bar as you tap as fast as possible for your chosen duration, then reports your CPS score. The Audio Reflex test works like the visual test but plays a tone instead of showing a color.

All results are automatically saved. The Stats screen shows a trend line chart across your recent sessions plus a timestamped log with colored category icons so you can see at a glance which test type each entry represents.

PERFECT FOR

• Athletes and esports players training reaction speed
• Students and professionals curious about their baseline reflexes
• Anyone running a self-improvement challenge or biometric experiment
• Friends competing for the fastest reaction time on the same device
• Coaches who want objective before-and-after benchmarks for their athletes
