Touch Latency Test

Touch Latency Test is a simple hardware diagnostic tool for measuring touchscreen responsiveness in real time.

The app helps you test how quickly your device reacts to touch input by displaying live touch latency, sampling rate, touch coordinates, and event statistics while you interact with the screen.

Key features:

• Real-time touch latency measurement

• Average, maximum, and current latency stats

• Touch sampling rate display

• Live latency graph

• Multi-touch support

• Touch coordinate tracking

• Overlay test mode for checking touch response over other apps

• Device information including Android version, screen resolution, refresh rate, and model

• Dark mode support

Touch Latency Test is designed for diagnostics, testing, and benchmarking. It does not improve touchscreen performance, repair hardware, or boost device speed. Results may vary depending on device hardware, Android version, display refresh rate, system load, and manufacturer touch processing.
