Solstice is a personal finance and habit-tracking progressive web app I designed and built with Claude as co-developer. It began life as an app called "Discipline" and was rebuilt and renamed into Solstice — pared down to the trackers I actually use and given a distinctive "Solstice HUD" look: a Jarvis/Iron-Man-inspired interface of holographic glass tiles, arc-reactor cyan and suit-gold accents, corner brackets, and drifting scanlines. The whole app is two files with no backend, no build step, and no dependencies; every byte of data stays on the device in the browser and it works fully offline.

Solstice has the option to export for backup compatability.
