BTController - Turn Your Android Into a Bluetooth Gamepad
BTController turns your Android device into a Bluetooth gamepad that can be used to control emulator games running on another device (the host). You'll need the app installed and enabled on both devices - the controller and the host - and the two devices must be paired with each other over Bluetooth.
Unlike traditional console gamepads, most modern Bluetooth controllers are designed to work across a variety of platforms and systems. Many feature built-in rechargeable batteries, while others require standard AAs that can be replaced when needed.
In addition to standard functionality, Bluetooth gamepads also provide unique features like vibration (haptic/tactile feedback) when pressing keys or buttons. Some even have a built-in speaker that can play tones, songs, or other recorded audio files.
The best Bluetooth gamepads offer premium ergonomics and features at affordable price tags, and they are compatible with PCs as well as consoles and mobile phones. They are available in a wide range of form factors, from sleek designs that sandwich your phone to portable handhelds that can be used to play games on the go.
