This tool measures stick drift precisely: it records analog stick positions while the sticks are untouched, magnifies the center of the stick's range, and grades the drift from None to Severe.
Stick drift is when an analog stick reports movement even though nobody is touching it. In games it shows up as a character walking on its own or a camera that slowly rotates. It is usually caused by wear or dirt in the potentiometer sensors inside the stick module, and it tends to get worse over time.
Set your controller down and start the test. For 10 seconds the tool records the position of both analog sticks on every frame while they rest at center. The magnified scope view shows every recorded sample at 4x zoom, so even sub-percent drift is visible. If you touch a stick during the test, the measurement automatically restarts.
Games ignore small stick movements inside a dead zone, typically 5-15% of the stick's range. If your drift stays under 5%, most games will never notice it. Drift above 10% exceeds many default dead zones and can cause unwanted movement, forcing you to raise the dead zone at the cost of responsiveness.
Light drift can often be fixed by cleaning around the stick base with isopropyl alcohol or blowing compressed air under the stick cap. Recalibrating the controller in its official software can also help. Persistent severe drift usually means the potentiometer sensor is worn and the stick module needs replacement.
