## Overview

- **Who it's for**: Product designers and UX teams who need to prototype complex, dynamic interactions (not just screen-to-screen flows) for apps, devices, and connected hardware — used across industries like automotive, IoT, MedTech, and gaming.
- **What you get**: A no-code tool for building high-fidelity prototypes with real logic: variables, conditions, and formulas drive interactions. It supports sensor input (motion, location, camera), voice, and hardware/IoT connections via ProtoPie Connect, and prototypes can be tested live across multiple devices at once (phone, tablet, wearable, vehicle screen).
- **How it works**: Import designs from tools like Figma or Sketch, then add interactivity by wiring triggers (touch, sensor, voice, data) to responses (animation, navigation, variable changes) on a visual canvas — no code required. Finished prototypes are previewed on connected devices or shared via a link.
