THE DIAGNOSTIC SUITE
We don't just tell you if a button works. We analyze the signal integrity, timing consistency, and sensor accuracy of your hardware. Here is how to read your results.
Analog Precision
Stick Drift Analysis
Measures the signal variance when the analog stick is physically centered (untouched).
Even a 1% drift can cause your camera to move on its own or disable 'Rotational Aim Assist' in FPS games. This test tells you exactly how much 'Deadzone' you need to set in-game to fix it.
Circularity & Error Rate
Plots thousands of stick inputs to see if they form a perfect circle or a restricted square.
High error rates (avg error > 15%) indicate bad calibration or a fake controller. If your stick makes a square shape, you lose diagonal movement speed in games like Rocket League.
Stick Resolution (Bit-Depth)
Counts the number of unique steps your stick can report across its axis.
Low resolution (e.g., 256 steps) feels 'jagged' or stair-stepped when aiming. High resolution (e.g., 65,000 steps) allows for pixel-perfect micro-adjustments in sniper scenarios.
Snapback Test
Measures the 'overshoot' when you flick the stick and let go.
If the stick bounces past the center point upon release, your character might accidentally turn around or look the wrong way. Essential for Smash Bros and fighting game players.
Input Latency & Speed
Polling Rate (Hz)
Calculates how many times per second your controller reports data to the PC/Console.
Higher browser-observed cadence can indicate more frequent visible updates, but this page should not be read as a lab-grade hardware polling certificate.
Input Jitter (est.)
Measures the consistency of the polling rate. A stable connection has low jitter.
High jitter means your inputs are arriving in inconsistent bursts, making aiming feel 'floaty' or unpredictable, even if the average speed is fast.
Buttons & Mechanics
Input Timeline
A timeline view of browser-observed button states.
Helps spot visible double inputs, though very short contact chatter between animation frames can be missed.
Pressure Sensitivity
Checks if buttons/triggers are digital (0 or 1) or analog (0% to 100%).
Crucial for racing games. If your R2 trigger only reaches 90% pressure, your car will never reach top speed. This test verifies the full range of motion.
Vibration Motor Test
Sends specific frequencies to the rumble motors.
Diagnoses loose internal weights (rattling noise) or weak motors caused by low battery levels.
