Triggers & Pressure

Adaptive Trigger Tester

Pull L2/R2 or LT/RT and watch live 0–100% pressure bars respond in real time. This adaptive trigger tester reads the analog travel of each trigger so you can confirm both sides register a clean, smooth ramp from rest to full press.

Worn or sticky triggers lose their lower range first, which costs you in racing and shooter games where partial pulls matter. Used as an adaptive trigger for PS5 tester PC players also rely on, the tool surfaces those issues instantly in any modern browser — no install, no signup.

Press any button to begin

Connect via USB or pair over Bluetooth, then pull a trigger so the browser detects your pad.

For a complete trigger thumb test, run several slow pulls and several fast ones — the fill bar should track your finger smoothly both ways with no sudden jumps or dead spots near the bottom of the travel. If you suspect a sticky trigger, our adaptive trigger tester and dedicated trigger finger tester drill together make the fault easy to spot before it affects your gameplay.

About

What this tool does

The adaptive trigger tester reads the analog pressure of your controller's left and right triggers and maps it to live 0–100% bars. Instead of a simple pressed / not-pressed reading, it shows the full travel of each trigger — so you can see exactly how your input ramps from rest to a full pull.

That matters because triggers are analog inputs. Racing games read partial throttle, shooters use light pulls for aim-down-sights, and a worn trigger loses its lower range first. By watching the fill bar track your finger, you can spot dead spots, sticky travel, or a side that no longer reaches 100%. Everything runs locally in your browser through the standard Gamepad API — no download, no account, and nothing leaves your device.

Which controllers it works with

Any controller that exposes analog triggers to the browser will work. That covers the large majority of modern pads:

PlayStation
  • DualSense (PS5)
  • DualShock 4 (PS4)
  • DualSense Edge
Xbox
  • Xbox Series X/S
  • Xbox One Wireless
  • Elite Series 1 & 2
Other
  • Switch Pro Controller
  • 8BitDo & third-party pads
  • Generic USB gamepads

For the most reliable analog reading, connect over USB in a Chromium browser such as Chrome, Edge, Opera, or Brave. Bluetooth works too, though wired tends to be steadier.

FAQ

Common questions

A trigger that stops short of full travel usually has internal wear or debris under the mechanism. Try a few firm full pulls — if the bar still caps below 100%, the trigger likely needs cleaning or service.
A healthy trigger produces a smooth ramp. Sudden jumps or a dead zone near the bottom point to a worn potentiometer or a sticky return spring.
The browser reads how far each trigger is pulled, not the motorised resistance the DualSense applies during games. It still confirms the trigger's analog range and travel are working correctly.
Press a button first to wake the pad. If there's still no reading, try a different USB port, re-pair Bluetooth, or refresh the page.
No. The test runs entirely in your browser. Nothing about your controller or your results is sent or saved off your device.
