Scroll Wheel Analyzer

Give your wheel / two-finger scroll a workout. We plot each delta so you can spot jitter or direction flips.

How this Scroll Wheel Analyze Works

Every tick of your mouse wheel, trackball, or two‑finger trackpad gesture emits a wheel event with a signed delta. We capture those deltas at your browser’s native sampling rate, plot them as bars, and compute running statistics—no installs, no data leaves your device. Typical high‑quality gaming mice show clean, even‑height bars. Sudden spikes, gaps, or direction flips usually point to a worn encoder or firmware debouncing issue.

✔️ Spot jitter from dirty scroll wheels
✔️ Catch direction reversals caused by faulty encoders
✔️ Compare physical wheel vs. two‑finger scroll on laptops
