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)

If you complain about features, usability or font size:

Yeah well, thats the idea of a personal app. You dont need to like it. It's my suit, it suits me. (̿Ĺ̯̿ ̿)
