Welcome to the Precision Movement Test This tool measures the smoothness and accuracy of you, your mouse or trackpad. Simply trace the dashed horizontal line as steadily as possible, and we’ll calculate your vertical jitter, average deviation, and precision score. A bit of fun, perfect for gamers, designers, or anyone wanting to view their pointer performance.
Trace the dashed horizontal line from left to right as steadily as you can. This measures your vertical “jitter” (deviation from perfect straightness).
Avg Jitter: The average vertical deviation from the center line. Lower values indicate better precision.
Max Jitter: The maximum vertical deviation during your trace. This shows the worst-case error.
Precision Score: A percentage indicating how closely you followed the line. 100% means perfect tracing with no deviation.
