A habit-building workout tracker. The premise is that the failure mode of most fitness apps isn't the workout — it's the friction between deciding to train and actually starting — so Equipless is built around routines that need little or no equipment and a UI that gets you into a session with minimal taps. Technically it was a testbed for Expo's server components pipeline in React Native, which at the time was new enough that building anything non-trivial on it meant figuring out the patterns as they emerged.
