Turn your smartphone or tablet into a high-precision, low-latency steering wheel and button box controller for driving and simulation games like Euro Truck Simulator 2 (ETS2), American Truck Simulator (ATS), Fernbus Coach Simulator, BeamNG.drive, and Assetto Corsa.

• 🏎️ Precision Steering Wheel: Dynamic configurable rotation degrees (180° up to 1080°) with customizable wheel diameter and auto-centering spring physics.
• ⚡ Ultra-Low Latency Binary Protocol: Zero-allocation packed binary UDP network stream delivering sub-millisecond responsiveness with negligible CPU usage.
• 🚦 Pro Linear Pedals: Smooth throttle and brake pressure control sliders with return spring mechanics.
• 🔘 Interactive Cockpit Matrix: Fully customizable button grid with support for:
  • Momentary buttons (Push & Release)
  • Toggle switches (On/Off)
  • 3-Stage rotary style switches (Off ➔ White ➔ Amber ➔ Green)
  • Realistic synchronized vehicle logic (directional turn blinkers, hazard flasher, ignition engine control).
• 🔍 Instant Host Auto-Discovery & QR Pairing: Effortlessly connects your mobile device to your PC companion via UDP subnet beacons or instant live QR camera scan.
• 🖥️ Lightweight Desktop Companion: Electron/React HUD dashboard with a native Win32 input feeder and zero background process spamming.
