Sound Master is a high-precision sound meter application designed for iOS devices. The application features a variety of features and functionalities.

As the app’s lead designer, I supported a team of subject matter experts in eliciting requirements, drafting hypotheses, and conducting preliminary user research to define a business value proposition of the envisioned product.

I helped the team proceed with user story mapping and facilitated several co-creation sessions, where ideas were proposed, wireframed, and prototyped in native iOS (Objective-C and Swift). I later conducted usability testing sessions with real users to confirm or reject the previously gathered hypotheses. Based on the feedback, I moved forward with a second iteration, leading to high-fidelity mockups.
