Local-first groceries/pantry management

[ryzokuken]

There's a number of apps for managing your pantry as well as making shopping lists and many apps of this sort tend to also allow recipe management as a cherry on top given they have nearly all the necessary information anyway. This has been further improved due to mobile platforms including a native bar code scanner however all existing apps including ones that are open-source and at least somewhat usable rely on server-side sync and other server features.

My understanding is that if the user only sets up the app on a single mobile device it should be perfectly usable without the need of a server at all and even multi-device functionality can be achieved by p2p sync without the need of a central server. Like all other lofi ideas the best part of all of this is that it would make the app the most scalable app of this category by removing completely irrelevant server costs.

One interesting use case for centralization in this category is for registries: you might need a barcode -> item registry or just a registry of recipes but those could technically achieved without the need of a central server by utilizing a blockchain... That said it might be too early to think of this part and maybe I should focus on building the MVP of the application instead.
