Lists

The Lists tab holds two shopping lists, Grocery and Household, and the machinery that learns what your household buys and puts it back on the list before you run out.

Adding and checking off

Typing something adds it. Tapping the box beside it checks it off, which records a purchase — the app's memory of what you bought and when, which is what everything on this page learns from.

• Undo. A check-off can be undone for a few seconds after the tap. The undo reverses the purchase too, so a mis-tap does not teach the app anything.
• This trip's check-offs stay in view, below the list and struck through, until the trip is over. A tap on one puts it back on the list, and reverses its purchase, minutes after the undo bar has gone.
• Moving an item. Hold an item's name to move it to another workspace. A checked-off item stays with its trip.

Regulars

Things the household buys on a rhythm — milk, coffee, dog food — become regulars. The app learns each one's rhythm from your own purchases and puts it back on the list at roughly the right time.

It only does this when it is confident. Otherwise it stays quiet, and a might be running low shelf under the list holds the guesses it is less sure about, for you to take or leave. Nothing is ever marked late or overdue: a regular that has not come back yet is simply not on the list yet.

A regular can be:

• pinned to a shop, so it comes back for that shop's trips;
• given a season, so a summer thing is not expected in January;
• told how much is usually bought, so a big pack and a small one are read as the same rhythm.

Regulars are managed from More → Settings → Regulars. A regular's own page also keeps one quiet fact: if it has been on the list across the last two or more trips to its shop and came home unbought each time, its row and its page say so — "Not found at Kroger on the last 2 trips there". That is a fact about the trips, never a badge, and it says nothing below two trips.

Shops and trips

The app learns which shop a trip was at from where the phone was when things were checked off, and asks when it is not sure. Shops and Recent trips are both in Settings.

Recent trips lists each trip inside the household's look-back window — ninety days unless you change it in Settings — with its day, how many things it bought and its shop. Opening a trip shows what it bought. A trip with no shop offers the shop picker right there; a trip that has one keeps the picker behind a Change shop button. Either way, choosing a shop re-attributes the whole trip.

Receipts and pantry photos

When the assisted features are on, the Lists home offers two ways in by photo:

• Scan a receipt. What was bought lands as purchases, as if you had checked each thing off.
• Photograph a pantry shelf. The app proposes what looks to be running low, and you decide what to track.

Tidy up

Now and then the app reviews the household's regulars and finds two that look like one thing, or one that looks like two. When there is something to tidy, a Tidy up card appears on the Lists home with its proposals, each to accept or decline. It carries no badge and never nags; when there is nothing to tidy, it is not there.
