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 ̿)

This isn't another Firebase clone — it bakes authorization into the data model (you specify access when you create facts) and uses an RDF-style facts/triples API plus CRDT/OT for real-time merges. The demo hooks (useKeyValueAttributes) and OpenID Connect support make the client story feel thought-through, so this is worth a look if you need server‑sovereign, multi-app data sharing rather than a client-first offline story.
Ambitious offline fitness app but local AI claims lack technical specifics.
Firebase alternative with graph data model and one-command Docker backend.
Headless testimonial API that lets agencies build custom widgets without SaaS fees.
Real-time sheets over Tor with zero external services—genuinely clever infrastructure for a niche audience.
