A grocery list that reminds you at the store

A reminder set for 6 pm goes off in the car, in a meeting, or at dinner — anywhere except the store. The useful reminder is the one that arrives when buying the thing is actually possible.

Why “remind me at 6” keeps failing

A grocery list has a strange failure mode: it is complete, it is accurate, and it is in your pocket while you walk past the store. Nothing about a list makes you open it. Time-based reminders try to fix that by guessing when you will shop, and the guess is wrong often enough that you learn to swipe them away.

A location reminder does not guess. You tell the phone which store, and the phone tells you when you are there — not at 6 pm, but at the moment there is a basket in your hand. Because it only fires when there are still items to buy, an empty list stays silent.

What a location reminder actually is

Your phone does not follow you around to make this work. The app hands the operating system a circle on the map — the store and a radius — and asks to be woken when you enter it. That is a geofence, and both iPhone and Android handle it in hardware, which is why it costs almost no battery: nothing polls GPS, and no app has to be running. How store reminders work goes through what the phone is really doing, what it costs, and where it is imprecise.

Detection is not instant. The operating system typically notices you have arrived within a few minutes, so a larger radius buys earlier warning. It needs background location permission, which you should grant deliberately. And it cannot work in a browser — no web page can register a geofence — so the reminder always comes from the phone app.

Three ways to get one

Apple Reminders, if everyone in the house has an iPhone. The built-in grocery list type sorts items into sections, and any list can have a location reminder attached. It costs nothing and is already installed. The limit is sharing: Reminders shares only between Apple Accounts through iCloud, so it cannot include an Android phone, and the reminder only ever goes to the person who set it.

AnyList, if you already pay for it. Location reminders are part of AnyList Complete — $9.99 a year for one person, $14.99 for a household, checked 17 September 2026. AnyList never transmits your location, which is admirable, and it also means the reminder can only notify the phone it is on. Home List vs AnyList covers the rest.

Home List, on iPhone or Android, free at one store. Pin the stores you use, link a list to each or keep one list for anywhere, and your phone reminds you when you arrive with items unchecked — with the app closed, from a locked screen. Premium ($2.99 a month or $24.99 a year, covering the whole household) extends the reminder to every store you shop at.

The part only a household app can do

The person in the store is not the only one who needs to know they are there. Turn on Live Alerts and the rest of the household is told — Sam is at Aldi with 6 items left — which is exactly the moment someone at home remembers the bin bags and adds them. The item lands on the shopper’s phone before the checkout.

Sharing is opt-in per person and can be switched off at any time. What travels is the store name and a count of items, never coordinates: nobody in the household can see where anyone else is, only that someone arrived at a store you all use. A cooldown stops lingering near a store from producing a stream of notifications.

Setting it up in Home List

Add a store from the Stores tab and pin its location — search for it, or use where you are standing. Set the radius: 500 feet for a store you only ever drive into, up to 10 miles for the one you pass on the way home. Link a list to the store, or leave it general so any list counts. Grant background location when the phone asks; it is what lets the reminder fire with the app closed. There is no schedule to set and nothing to remember to open.

The whole thing can be tried without an account. Start a household, pin one store, and the reminder there is free for as long as you like.
