Touch Sample Rate Tester is a utility application designed for Android devices that allows users to measure the touch sampling rate of their touchscreen. This tool provides insights into both the hardware sampling rate and the actual rate at which touch events are processed by the Android system. Users can discover whether their device's advertised touch sampling rates, such as 240Hz or 300Hz, are reflected in real-world performance, given that the effective touch event rate is often capped by the device's screen refresh rate.

The app features two main functionalities: it enables users to check the hardware sampling rate of their touchscreen and the rate at which touch events are invoked. By utilizing this application, users can gain a clearer understanding of how their device handles touch inputs, which can be particularly useful for gamers or those looking to optimize their device's performance.
