WhatTo shared shopping list with milk, bread and eggs and a progress bar
Your shared list, in real time

Sound familiar?

You’re at the supermarket and text your partner: “Do we need milk?” No reply. You buy it anyway — and come home to find two cartons already in the fridge.

Your flatmate picks up groceries on the way home but doesn’t know about the three items you added to the WhatsApp group an hour ago. Nobody checks that chat anymore.

You keep a shared note, but half the household forgets to open it. Items get lost between messages, voice notes and sticky notes on the fridge.

WhatTo replaces all of that with one shared list that updates instantly on everyone’s phone — whether you’re on the sofa or already in the shop.

Real-time sync for your entire household

Every item you add, check off or rearrange appears on all connected devices within a second. No refresh button, no “did you see my message?” — just a list that’s always up to date. WhatTo uses real-time sync so your partner sees changes the moment you make them, even on a slow mobile connection.

Store Mode — your household knows you’re shopping

Tap the cart icon and everyone in your room gets notified that you’re at the store. They can add last-minute items — butter, bin bags, that one spice you always forget — and you’ll see them pop up on your screen instantly. No more “are you still at the shop?” texts. When you’re done, simply leave Store Mode and the list resets for next time.

AI suggestions that learn what you need

WhatTo’s AI analyses your shopping patterns and suggests items you buy regularly. Forgot to add eggs? The suggestion card reminds you. Over time, the recommendations get smarter — so building your weekly list takes seconds instead of minutes. You can also use it in household planning beyond just groceries.

Sections for different stores or categories

Organise your list by supermarket aisle, store or category. Create a section for fresh produce, one for the bakery and one for the chemist. When you’re in the shop, work through one section at a time instead of scrolling up and down a single long list.

Receipt scanning and expense splitting

Done shopping? Photograph your receipt and WhatTo’s AI extracts every item with its price automatically. Assign items to household members and see who owes whom — no spreadsheets needed. Perfect for flatmates splitting the weekly shop or couples tracking grocery spending. Learn more on our receipt scanner page.

Why not just use WhatsApp or a notes app?

WhatsApp groups work — until someone sends 40 messages and your shopping list disappears. Notes apps like Apple Reminders sync between your devices, but sharing with housemates means granting access to your entire account.

WhatTo is built for shared shopping. Everyone gets their own account, items sync in real time, Store Mode tells the group you’re at the shop, and the AI receipt scanner splits costs automatically. No workarounds, no screenshots of lists — just one place where everyone can see what’s needed.
