Cercle.

Cercle keeps one on-device file for a regular potluck circle you meet through posts and group threads. Write who usually comes, a photo if you want, food they avoid, and whether the host can reheat or chill dishes. Before the next meal, open Prepare to see those faces and limits beside what people brought last time. Copy a short note and paste it into the group yourself. After eating, tap a person, write the dish, and add a photo or a short recording if you want. Nothing is posted for you, and nothing is transcribed. It does not pick a date, split costs, or replace a shared sign-up thread.
