The International Tennis Federation (ITF) wants to standardize global tennis rankings through its newly created World Tennis Number (WTN) system, which assigns tennis players a ranking based on their past match results.

ITF, which is the governing body of the tennis around the world, decided to create a mobile app to make it easier for players around the world to claim their WTNs and access relevant information about past matches, rankings, and other players. Our small (but mighty) product team of three put together a proposal to make the app. In a mere 48 hours, we went from frantic ideation to unsightly concept sketches on a whiteboard to fully branded, high-fidelity product mockups.
