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

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!

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.

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.
