My New Game pad With Bluetooth wireless 🛜 does work on this app. I figure fix control these Game pad Controller how to make these stayed 'ON', because I just play the Mech Arena app game online all-day. I enjoyed these use it all the time, sometime I don't understand why my Game Controller does itself automatically shut off by itself, I'm not finish the game? Why itself interrupt shut off by itself? I figure how to fix override my Game Controller 🎮 suppose be stayed "ON" on app?... Thanks...

Hello! I have an Aolion K20 TMR joystick. I used to have an issue where, after turning on my computer for the first time, the joystick would go to sleep and fail to reconnect. This app helped me update the firmware from version 4.08 to 4.15. The joystick was recognized immediately in the app without any problems. Now, after the update, everything works perfectly. Everything’s great — thank you so much!

Almost trashed my Hyperion Pro controllers, and was losing my mind because this app didn't seem to do ANYTHING. Turns out, you have to touch where it says "Bluetooth" so that it will ask for permission to look for the controllers. Then it works as advertised. Fantastic app, and happy to finally have zero Dead zone :D

This app let me change the button arrangement on my generic Nintendo Switch controller to match the button arrangement of an Xbox One

App is broken, it keeps getting a bug where my controller won't connect and if ID does connect I get kicked out the app

★☆☆☆☆ Adhiraj Singh · Feb 18, 2026

It is a useless app, I bought evofox duck 2, but it is not showing any game, evofox has fooled the public.

★☆☆☆☆ Ashlee Przelomiec · Feb 19, 2026

Doesn't work. Got it to connect to the controller but doesn't load any settings. Hitting the gear icon just shows a loading wheel and then refreshes the page. Useless.

★☆☆☆☆ Howard Blatz · Apr 30, 2026

Refuses to connect to Bluetooth, no viable PC/wired option available. They work technically, but they refuse to shut off while connected to the Switch 2 and continuously drain the battery. Can't update the firmware because the app constantly fails to connect to the controllers.
