I started practicing Brazilian Jiu-Jitsu over the summer of 2026 and was looking for an app to track my progress. Finding few options, I decided to build my own.

The backend, including authentication, is built with Supabase. This is my second foray into iOS development after building and shipping a very simple guitar tuner app to get a feel for the process.
