About

ThrottleCard is a feature-rich model railway throttle application built exclusively for the Apple ecosystem, covering iPhone, iPad, macOS, and Apple Watch. Designed for hobbyists who want both beauty and power, the app delivers a vintage railroad aesthetic through analog and digital gauge options, vintage-style fast clock displays, and deeply customizable themes including pro dark modes for premium subscribers. The app connects seamlessly to WiThrottle-compatible and DCC-EX command stations via automatic network discovery or manual connection, requiring no additional middleware. Users can choose locomotives from a photo roster or enter DCC addresses manually, then operate them using precise speed controls with haptic feedback. Full function support (up to 28 DCC functions) covers lights, bell, whistle, and more. ThrottleCard also includes native DCC-EX integration for reading and writing Configuration Variables (CVs) on both the programming track and mainline, making decoder setup straightforward for beginners and experienced operators alike. Advanced features such as decoder database templates and real-time track monitoring are planned for future updates. Additional highlights include custom railroad logo uploads, landscape-mode roster optimized for handheld operation with game controllers, route and switch management with visual feedback, and a big-screen optimized UI for iPad and Mac. ThrottleCard is ideal for home layout operators, club members, and serious model railroad enthusiasts who want a polished, all-in-one control solution.
