ProtoPie

ProtoPie is a professional interactive prototyping tool designed for designers, UX researchers, and product teams to create realistic, high-fidelity prototypes without writing any code. It enables users to build complex interactions, gestures, and multimodal behaviors that closely mimic real-world user experiences across a wide range of devices and platforms. Unlike traditional prototyping tools that often limit interactions to simple screen taps or transitions, ProtoPie supports advanced sensor input, hardware integration, and multi-device communication, making it particularly suitable for prototyping automotive human-machine interfaces (HMI), smartwatch apps, game interfaces, TV and production systems, as well as standard mobile and web applications. One of the core capabilities of ProtoPie is its ability to simulate realistic hardware interactions. Users can incorporate device sensors such as gyroscope, accelerometer, microphone, and proximity sensors, allowing prototypes to respond to rotation, shaking, voice commands, or device tilting. This is especially valuable for prototyping automotive UX, where interactions often involve steering wheel controls, touchscreens, gestures, and voice commands. ProtoPie also supports multi-device interactions, enabling designers to create prototypes that communicate between a phone, a smartwatch, and a car dashboard simultaneously, providing a true cross-device experience. The tool integrates seamlessly with popular design tools like Figma, Sketch, and Adobe XD, allowing designers to import their existing design assets and turn them into interactive prototypes with minimal effort. ProtoPie's interface is built around a timeline and condition-based logic system, where users can define triggers (e.g.
