Best Grocery Price Comparison Apps in Australia (2026): Woolworths, Coles, Aldi & IGA Compared

Updated July 2026 · 8 apps tested against the same criteria

If you have ever stood in a Coles aisle wondering whether the same tin of tomatoes is cheaper at Aldi this week, you already know why grocery price comparison apps exist. There are more of them in Australia than most people realise, and they are not interchangeable — some only cover two chains, some lock the useful bits behind a subscription, and some are really deal feeds rather than genuine price comparison tools.

We looked at eight apps that Australians actually use to compare Woolworths, Coles, Aldi and IGA prices, including our own app, Grozeries. To keep the comparison fair, every app below is judged against the same five criteria:

• Store coverage — all four major chains (Woolworths, Coles, Aldi, IGA) or only some of them
• Cost and account — genuinely free, or paid/subscription features, and whether you need to sign up
• Notifications — push alerts tied to items on your own list/favourites, versus a general deals feed or email digest
• Shopping list logic — whether the list can automatically sort or split by cheapest store
• Platform — native app, web app, or browser extension

Every claim below is based on what each app currently states on its official app store listing or website as of July 2026. Features change, so it is worth spot-checking the app store page before you commit to one.

At a glance

Frugl

Frugl was one of the earlier apps to properly cover all four major chains, and it still shows dietary and allergen filters that most competitors don't bother with, plus a shopping list that can split itself across Coles, Woolworths, Aldi and IGA depending on where each item is cheapest. Households managing allergies or intolerances get more here than almost anywhere else in this list.

Trade-off: its App Store and Google Play listings show no update since September 2022, and its marketing website returned an error when we checked in July 2026. The features may still work, but a multi-year gap in visible maintenance is worth factoring in before you rely on it.

GroceryWise

GroceryWise is refreshingly simple: no install, no account, no email required just to browse. It pulls Wednesday catalogue specials for Woolworths, Coles and Aldi (plus Chemist Warehouse) into one page, and its methodology page is unusually transparent about where the data comes from.

Trade-off: it doesn't cover IGA, there are no push notifications (only an optional weekly email), and it only surfaces catalogue specials rather than a full everyday price comparison. A promised "cheapest basket" builder and browser overlay were both listed as upcoming, not live, at time of writing.

Grozeries

Grozeries is our app, so judge the trade-offs, not just the pitch. It compares Woolworths, Coles, Aldi and IGA side by side, and you can use every part of it — browsing, comparing, favouriting, notifications — without creating an account or handing over an email address. Favourite a product and Grozeries pushes a notification the moment it goes on special; add items to your shopping list and it will tell you which store has each one cheapest, so you're not stuck deciding between one big shop and the best price.

The specific combination — all four chains, push notifications tied to your own list, an auto-sorted shopping list, and no account requirement — is not something every competitor offers together. Frugl comes close on features, though its maintenance history is uncertain; most of the others gate at least one of these behind a paid tier or a missing chain. So rather than claim to be the only app that does this, it's fairer to call Grozeries one of the only apps that combines all of it without a subscription or a login screen.

Trade-off: Grozeries doesn't have a meal planner, dietary/allergen filtering, or a browser extension — features that Frugl, WiseList and WhichGrocer each offer in their own way. If those matter more to you than free push notifications and account-free access, one of those apps may suit you better.

Half Price

Half Price does one thing and does it without any fuss: it lists half-price (50%+ off) specials from Woolworths and Coles, refreshed every Wednesday morning, and lets you build a basic shopping list from them. If all you want is a quick scroll through this week's biggest markdowns, it's fast and free.

Trade-off: it only covers two of the four major chains — no Aldi, no IGA — and it only shows items that are already at 50% off, not a general price comparison across everyday products. There's no cheapest-store logic (with two stores and deal-only data, there isn't much to split) and no push notifications on its official listing. It's a half-price bargain scroller, not a price comparison app in the fuller sense the other apps on this list aim for.

Save On Groceries

Save On Groceries covers all four major chains and centres its experience around a wishlist: add products you buy regularly, and it pushes a notification when the price drops or the item goes on 50%+ special. A nearest-supermarket finder and expiry reminders round out a genuinely personal-alerts-first design.

Trade-off: its own FAQ suggests an account is effectively required to unlock price comparison rather than just basic browsing, and we couldn't confirm an auto-split shopping list feature on its official listing. Store ratings also point to a smaller, newer user base than some competitors.

TrolleyChecker

TrolleyChecker casts the widest net in this list, pulling in comparisons for Big W, Chemist Warehouse, Costco and Amazon alongside the four supermarkets, and you can search and compare without ever creating an account. An optional paid tier adds AI ingredient and health checks for people managing specific diets.

Trade-off: it's a web app only, with no native app and no push notifications. Its own guides note that Aldi's everyday range is often missing from live results (Special Buys are curated separately), and we found no official claim of an auto-split shopping list — lists exist, but the cheapest-store logic isn't part of the pitch.

WhichGrocer

WhichGrocer's browser extension is genuinely useful if you already shop by browsing Woolworths or Coles online — it overlays price data directly on the retailer's site as you shop, and its "Price Targets" feature emails you when a product you're watching hits your price. It's also the only app here that compares beyond groceries, into Chemist Warehouse and Priceline.

Trade-off: the free tier is limited to Woolworths and Coles; Aldi, the extension sync, and the auto-calculated cheapest-store list all sit behind a roughly $2/month Premium subscription. Free-tier shopping lists are also capped at a small number of items.

WiseList

WiseList is less a price-comparison app and more a household organiser that happens to include one: on top of comparing Woolworths, Coles and Aldi, it has an AI meal planner with a large recipe library, pantry tracking, and bill comparisons for energy and broadband. For a family juggling meal planning and groceries together, that breadth is hard to match here.

Trade-off: it doesn't cover IGA, requires an account to use, and its actual price comparison and "Smart Split" shopping list sit behind the paid WiseList+ subscription — the free tier is mainly the list and meal-planning organiser, not the price comparison itself.

How to choose

There isn't a single "best" app here — it depends on how you shop.

• Notification-driven shoppers who mainly want to know when specific products go on special should look at Grozeries, Frugl, Save On Groceries or WiseList's watch list — all tie push alerts to a personal list rather than a general feed.
• Families meal-planning around the weekly shop will likely get more out of WiseList's recipe and meal-planner tools, even accounting for the subscription, or Frugl if allergen filtering matters.
• People who shop mainly online through the Woolworths or Coles website may prefer WhichGrocer's browser extension, which overlays comparisons as you browse rather than requiring a separate app.
• Anyone who just wants a fast, no-signup half-price scroll and doesn't care about Aldi or IGA can get that from Half Price in under a minute.
• Shoppers who want all four major chains, free, without an account, and alerts tied to their own list — that's the specific gap Grozeries is built to fill.
• Anyone comparing beyond groceries — pharmacy items, discount department stores, or wider retail — is better served by TrolleyChecker's broader retailer set.

Whichever you land on, it's worth checking each app's current store coverage and pricing yourself — this is a fast-moving category and features shift often.
