Add items to your shopping list using simple, plain-English names like "semi-skimmed milk", "chicken breast", or "wholemeal bread". Your list is saved securely in your browser's local database — no account required, works offline, and your data never leaves your device. Add as many items as you need before your weekly shop and check them off as you go around the store.

Tap "Compare Prices" and SmartList searches its database of current supermarket prices across Tesco, Aldi, and Sainsbury's. Each item on your list is matched to the closest product at each store, and you'll see the lowest and highest price for your full basket at a glance. No more manually checking three different supermarket websites — SmartList does it all in one place, before you leave home.

Armed with per-item price data, you can choose the cheapest store for your full basket, or identify the specific items that are significantly cheaper elsewhere and plan a split shop. Over a typical week, UK families who compare prices before shopping save between £15 and £30 — adding up to over £1,000 a year. SmartList puts that information in your hands every week, for free.
