Worked perfect and seamless after minor fiddling to get phone BT to device. Used app with a JC200 wireless controller to use with a Nintendo Switch. Initially couldn't connect to the JC200 but then noticed a Pro Controller would pop up on BT scan each time. Paired to that and then in the app screen it saw the jc200, updated firmware, reset connection, the buttons, rgb and testing.....all worked great for features and setting key mapping.

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

Remember when you didn't need an app and could buy a working game pad that needed no setup? Machienke game pad started behaving as though the l2 and r2 buttons (triggers) were always pressed. Manual said I should install an app and fix it. No guide provided in app, and after 2 days of trying to fix in the settings I gave up and bought an original controller. Edit: is always on in the background. Is this sketchy app stealing my data too?

Didn't even work. No connected controller is showing. Tried using different devices.

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.
