It is a familiar pattern: the list app loads perfectly at home, then in aisle 7 — a basement surrounded by concrete — it spins forever. You end up shopping from memory and coming home without the important stuff.
The full list available even in airplane mode.
Marking items must work identically with or without internet.
When signal returns, changes push themselves — you never think about it.
If someone else checked the same item, the lists merge cleanly.
The technical difference is keeping data on the device and syncing later, instead of asking the server for every tap. That is what "offline-first" means.
Quick test: put your phone in airplane mode and open your list app. If it does not work completely, it is a home app, not a store app.
ShopList is offline-first: the list lives on your phone, works with zero signal in the supermarket basement, and syncs itself when you walk out.
