Technology is amazing. We may not have flying cars yet, but you can transform a cell phone into a virtual controller to play computer games. All you need is an app like this one and an Android device.
A controller on your smartphone
MAXJoypad is an easy-to-use app for players to use an Android smartphone or tablet as a virtual remote control to play PC games. To use it, you need to download the APK file to your mobile device and have the program on the computer. Then simply synchronize them over the wifi or Bluetooth, and that's it!
One important advantage of this app is that you can create different profiles and customize several controllers based on your tastes, games, and needs. You can configure the controllers' buttons the way you want and disable the ones you are not using.
MAXJoypad replaces your actual game controller and lets you play PC games and emulators using the power of your Android smartphone or tablet.
This app is compatible with Windows games. You can use it to play more conveniently, just as if you had a physical controller. On the other hand, it also has multiplayer options so up to four players can play simultaneously.
