Button Speed Test
Pick one button, choose a timer, and mash only that input. Held buttons do not repeat because the counter uses edge detection.
Speed Stage
Only the selected button counts. Other button presses are ignored.
Connect a controller, choose a button, and press Start test.

What this tool measures
The score tracks how many clean button edges you can produce in a fixed time window. Holding a button will not inflate the result because only new presses are counted.
Peak burst
Peak Burst shows the highest number of valid presses registered within a one second rolling window. It is useful for short explosive tapping speed.
Use cases
This page is handy for controller challenge modes, accessibility tuning, and checking whether one shoulder, trigger, or face button feels slower than the others.
