LFExtremeReaction

Dear friends, would you like to know how your responsiveness is?
This is a test reaction software. When you click the start button, it will randomly change the background color of the current interface, and then click the stop button with the fastest speed, so that it will record your reaction time. It also counts your test time each time, which will help you see the fastest response time, the slowest response time and average time, and will also allow you to improve your responsiveness as much as possible. This software is free and interface-operated. Convenient and simple, user experience is good, hurry and download and try it!!!
