Frequently asked questions
Why is my reaction time worse here than in a game?
A browser adds a frame or two of latency on top of your display's own. Use this to compare runs on the same machine, not to compare against someone else's screenshot.
Should I lower the target size?
Smaller targets separate precision from raw speed. Start at the default and shrink it once your accuracy is comfortably above 90%.
Is the Mouse Accuracy Test free?
It is free, with no account, no trial and no daily cap. Every device tests tool on inputtesthub.com works the same way: open the page and use it.
Is the Mouse Accuracy Test safe to use with private information?
No. The Mouse Accuracy Test runs entirely in your browser using JavaScript. Because the work happens locally, the page also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
What is the Mouse Accuracy Test used for?
The most common reasons people reach for it: comparing two mice or two sensitivity settings. Warming up before playing. Checking whether a new mouse pad changed anything measurable. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Does the Mouse Accuracy Test need an app or a driver?
