Runs on iOS and Android. The demo above is the same app compiled for the web.
It works with no signal. Every phone keeps a full copy of the club. Screens never wait on the network — there isn't a single loading spinner in the app. Changes queue up and sync when the signal comes back.
Security is in the database, not the app. Anyone can pull apart an installed app, so the rules live in Postgres where a modified app can't reach them. I found and fixed a hole that let any club member make themselves an admin, then wrote a test that signs in as two real users and proves it's closed.
It's tested. 950 assertions covering the rules that matter — who can set a lineup, when voting closes, how a record gets beaten. Five checks run on every push and finish in about 90 seconds.
A working demo, a handful of source files worth reading, and screenshots. It's a sample rather than the product — the full app is private.

Happy to walk through any of it.
