I have decided to revoke my initial 5 start rating because the has started misbehaving since the last 3 updates I did. whenever I start a game, it stops working, the little button at the top disappears and then reappears whenever it wants to. It also disappear and stops working in the middle of the game This has become more frequent. I have purchased the full app and expect the best experience. please fix it and I'll give my 5 stars back.

I use this app mainly to map my keyboard and mouse control to play on a bigger screen, and so far it works really well. Kudos to the dev! And the price for life-time VIP purchase is also quite cheap for something this useful!

*PRO Version* Simple and effective. Had some issues recently while playing R6Mobile and contacted support, updated app and all working again. I can recommend app. I come from playing on PC and I use mouse and keyboard without issues. Gamepad was configured too and no problems. If UI can be worked for a modern look that would be a 6/5 stars.
