Reaction Time is a lightweight C++ utility designed to accurately measure your reaction speed using raw HID input for maximum timing precision. By bypassing higher-level input layers, the application minimizes latency and provides more reliable, consistent results—making it suitable for both enthusiasts and developers who want precise measurements.
In addition to reaction testing, the app includes integrated one-click CPU and GPU benchmarks. These allow you to quickly evaluate system performance, compare hardware upgrades, and observe how configuration changes impact real-world responsiveness. Built-in tracking makes it easy to monitor performance trends over time, helping you understand how daily system conditions or background load may influence your results.
With its minimal footprint and fast execution, Reaction Time is ideal for users who want a simple yet technically robust tool for measuring both human reaction speed and system performance in one place.
*Supports binding reaction time test button to mouse, game controller or keyboard.
*v0.7 adds Audio Cue option
