Grocery price comparison apps in the UK (2026)
There are three kinds of tools to save on your food shop: price comparison sites and apps (search a product and see its price in each supermarket), supermarket and loyalty apps, and apps that read your receipt and show your real spending as well as comparing prices. Scanio is one of the last kind.
Scanio App
Free app for iPhone and Android by Sibelion Lab. You snap your supermarket receipt and it saves every item, price and shop. From that it shows what you spend each month by supermarket and category, and compares prices of more than 130,000 products from supermarkets in the UK and Spain, updated daily. It also has a shared shopping list.
- Best if: you want to know what you really spend and where your own shop is cheapest.
- Price: free during the beta.
Other tools people use in the UK
Based on each service’s public information, checked on 06/11/2026. Check what each one covers before relying on it.
- Trolley.co.uk: a price comparison site and app where you search products and see their price across UK supermarkets.
- Supermarket and loyalty apps: useful for member prices, offers and online orders at that chain, but they do not compare with other supermarkets.
- Food-waste apps such as Too Good To Go: not price comparison, but a way to buy surplus food for less.

Frequently asked questions
What is the best app to compare supermarket prices in the UK?
It depends on what you need. To check one product across supermarkets, a price comparison site works; to know what you spend and where your own shop is cheapest, an app that reads your receipts such as Scanio.
Is Scanio the same as Scandio or ScanIO?
No. Scanio App (scanioapp.com) is the supermarket receipt and price comparison app by Sibelion Lab. Scandio is a loyalty-card wallet app and ScanIO is a business invoicing tool; they are not related to us.
Does Scanio work in the UK?
Yes. Scanio compares prices from supermarkets in the UK and Spain, and the app is available in English. It is free during the beta.
