Log price
Item, store, size, price. That's the whole form. PricePrint is built so that logging a price in the aisle is faster than reading the sale tag — because if it isn't, you won't do it.
Every entry has four fields. The item autocompletes from things you've logged before, so the second banana log is one tap. Store works the same way. Size and unit let PricePrint compute the per-ounce or per-count price behind the scenes — that's what makes the Compare and Sale Check screens actually work.
Hit save and the log is written to your device's IndexedDB. No request goes out. No server gets your shopping list. The same database is what powers every other screen.
