A grocery list is a plan for spending money, and most list apps pretend otherwise. You write down forty things, walk the store, and learn the total at the register. Sherpsy can tell you before you leave the house — if you want it to.
Opt in, per list
Price tracking is off by default, and it is a setting on the list, not on the household. A weekly grocery run might want it; the packing list for a camping trip does not. Turn it on and every line gains an optional price field, and the list gains a running total at the bottom that updates as you tick things off and add things in.
The second time is free
The part that makes it bearable: you type a price once. The next time anyone in the household adds the same item to a tracked list, the last price you entered comes with it. Milk is milk. You correct it when the number changes, not every Saturday. Over a few weeks the list fills in on its own, and the total at the bottom becomes a real number rather than an aspiration.
The receipt should confirm what you already knew, not tell you.
It reaches the meal plan
Because recipes and lists already talk to each other, the same prices flow upstream. Plan a week of dinners and Sherpsy can estimate what the week's ingredients will cost from what you have paid before — an estimate, labelled as one, with the items it could not price called out rather than silently counted as zero.
None of this is a budgeting app. There are no categories to file things under and no charts to feel guilty about. It is one number, at the bottom of a list you were already keeping, that answers the question you were going to ask at the register anyway.
