Open Source Android Game Controller Apps

BikeControl is a cross-platform tool aimed at enabling control of trainer apps (cycling/indoor training apps) using hardware controllers such as bike shifters, dedicated remotes (e.g. Zwift Click, Zwift Ride, Zwift Play), gamepads, or even generic Bluetooth HID devices. Instead of connecting to the trainer directly, BikeControl acts as a bridge: when you press a button or lever on your controller, it intercepts the input and simulates corresponding keyboard/mouse/touch events for your trainer application. This allows you to perform actions like virtual gear shifting, steering, changing workout intensity, controlling music, etc., even if the trainer app doesn’t natively support those controllers. It works on different platforms: on Android, it uses the AccessibilityService API to send simulated touches to whatever app window is active; on desktop (Windows/macOS), it can emulate key/mouse input via configurable keymaps so users can tailor controls.

Intiface Central is a free, open-source application that provides a centralized interface for connecting and managing compatible intimate devices. Built around the Buttplug device control library, it enables communication between supported hardware and third-party applications. Users can discover connected devices, configure their settings, and manage device connections through a graphical interface. The software acts as an intermediary between applications and hardware, reducing the need for individual programs to implement device-specific communication protocols. It supports a variety of compatible devices and connection technologies, depending on the hardware. Developers can integrate device functionality into their applications through the Buttplug protocol. Available for Windows, macOS, Linux, Android, and iOS, it provides a flexible environment for device connectivity and application interoperability.
