Worked great with my wired Logitech Extreme Pro joystick.This app did exactly what it said it would. It let me test my controllers and joysticks and see if each button, toggle and axis was recognized. I see several people gave this app a low score because their joystick / controller wasn't seen which isn't really fair because telling you your device isn't connecting is a valid testing response.

This app successfully detects but mis-identifies both my SteelSeries "Nimbus " and Sony "DualSense" game controllers. The app's voice assistant tells me they are unknown devices and the display (GUI) flags them as unknown.Despite that mis-identification, this app seems to successfully test most* of the buttons on those game controllers. However, it FAILS to fully test the right hand joystick on my Sony DualSense. For some unknow reason, it only shows movement along the X-axis no matter how I move the joystick around. Yet, it show perfectly the movement in all directions (XYZ axis) for the left-hand joystick.

...but after fighting my my Dual Sense Controller 4 fir at least 6 hours on various days... this app was a total savior! resident evil 4 just didnt see the controller, but once I opened this app - it worked like a charm. Devs, thank you so much! I wish you the best

Worked instantly for 2 PS4 Controllers when plugging them in, very responsive and helpful visuals.Be aware, has a voice assistant that is very loud and unnecessary, but otherwise perfect app!
