Yeah well, I build this self-hostable, PWA-ready fitness tracking app.

This is less about the app itself, there are probably dozens of them out there. This is more about me being fascinated about the idea of "personal apps": AI enables us to just build something that perfectly fits our indivual requirements - like a tailor-made suit.

None of the apps I know matched my requirements, some of them come with a subscription, some required an account. So I build F1L0. It would even work as a static HTML page with no backend services - like on GH Pages. I just needed a backend to add synching support with Firebase.

Repo: https://github.com/nickyreinert/f1l0

Features:

- custom training blocks and excercise of course - custom train/pause routine - simple plain data model that can be exported to ask AI for trainign advice - supplement support - did you take your "meds"? - progress tracker with some simple charts - using Firebase to sync (right now only Google Accounts are supported)
