BikeControl
Do virtual gear shifting (and more) in any rider app
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. -

Saber
The cross-platform open-source app built for handwriting
Saber is the notes app built for handwriting. It's designed to be as simple and intuitive as possible, while still delivering unique features that you'll actually use.

You can sync your notes across devices knowing that they are encrypted and stored securely, and not even the server can read them. Notably, it can invert your notes when you're in dark mode. This allows you to write with white ink on a black background, which is much easier on the eyes in low-light environments like when the teacher turns off the lights in class. Images and PDFs are also inverted, so you can still use a digital printout or a textbook without the fuss. Saber uses a dual-password system to protect your notes from anyone but you, even if they have complete control over the server. -
