Case Study: Surfitlocker achieves a code-free, user-tested mobile prototype with Justinmind

Surfitlocker - Customer Case Study

Surfitlocker is a surf and paddle-board rental app founded by Bill Rollinson to help travelers quickly find, reserve and pay for the right board. Bill needed a way to prototype a polished, mobile-first user experience without coding—one that could be built offline during his commute, shared with partners for feedback, simulated on devices, and tested with real users before development.

Using Justinmind, he created high‑fidelity, interactive wireframes that were easy to build and simulate on an iPhone, allowed partner collaboration and streamlined communication with developers. The result: rapid UX iterations, validated usability with customers and partners, clearer developer handoffs, and a production-ready prototype that Bill continues to use to test and refine the app.
