Receipt logging

Receipt logging is the thirty-second rhythm of opening Gluten Hero after a grocery trip and entering the gluten-free items from that receipt: the store name, the items, the gluten-free price, and the regular price of each item when the user noticed it on the shelf next door. The faster the rhythm, the more honest the year-end picture.

The form is intentionally minimal. Store name, date, optional photo of the receipt itself, then a list of line items. Each line item has an item name, GF price, regular price, category, an optional GF-Only flag, and an optional note. The category list is small and reuses across receipts. Restaurant rows have a slightly different shape (the Restaurant venue toggle on the receipt-level Log Items form), with "menu price" and "GF surcharge" instead of the full GF-vs-regular pair, since restaurant checks rarely itemize that way.

The thirty-second target matters because the alternative (saving every receipt for the weekly catch-up session) does not survive. A receipt that has been folded into a wallet for ten days has lost some of the information the user could have noted in the moment. Phone-based logging in the parking lot, before the next thing claims attention, is the rhythm that holds.

What the rhythm produces, in aggregate, is the comparable basket and the GF premium on the household's year-end report. The Insights tab cards (cost ratio, average extra per item, projected annual) all read from the same logged-item dataset.

A side benefit of the rhythm is that the household sees the premium in real time, not as a year-end surprise. The dashboard hero card on Gluten Hero updates with each receipt; the running total is the household's running cost of celiac.
