I took some screenshots to give better context to my answers below: https://imgur.com/a/5Vx9aOR https://imgur.com/a/5Vx9aOR To initialize an item, you take a QR code off a sheet of QR stickers (each one has a random v4 UUID as part of the web app URL) and choose a sharing method. In the case of eggs, I would simply enter whatever I paid for the eggs, and it is up to the roommate that scans the code to decide whether to take it or not. There are four "sharing schemes" supported so far - share by quantity, by rotation (so someone can join the rotation to replenish something like a spice), by percent (so someone can offer/claim 25% of a leftover pizza), or the whole item (probably ideal for the bag of chips example). The whole system is very hands-free and opt-in, and everything stays synchronized with Splitwise (I wanted to add some screenshots of that bit, but my roommate's names were all over - I might set up an example or GitHub repo for this project some day).
