About this app

CartChkr helps Australian families spend less on their weekly groceries — without changing how they shop.

Fill your cart at Woolworths or Coles as usual, then tap Scan. CartChkr checks every item in your cart against the other store and shows you, line by line, where it's cheaper, the same, or dearer. When something costs less at the other store, move it across with a single tap — CartChkr adds it to cheaper store's cart and removes it from the dearer one.

It works both ways: scan from Woolworths or Coles, and move items in either direction.

WHAT YOU GET
• Item-by-item price comparison between Woolworths and Coles
• Smart matching checks brand, size, even specials/multi-buys
• One-tap Move to shift cheaper items to the other store's cart
• Works both directions (Woolies to Coles, or Coles to Woolies)
• Your running total and potential savings updated as it scans
• Save the matches you like so they're remembered next time

HOW IT WORKS
1. Sign in to your Woolworths and Coles accounts (your logins stay on your device).
2. Add items to your preferred store's cart.
3. Tap Scan — CartChkr compares every item against the other store.
4. Tap Move on anything cheaper to switch it across.

FREE TO COMPARE
Scanning and full price comparison are free. Unlock one-tap Move with a Lifetime or Monthly option.

PRIVACY
CartChkr runs the comparison on your device and only ever talks to Woolworths and Coles using your own session. We don't collect or sell your personal data.

CartChkr is an independent app and is not affiliated with, endorsed by, or sponsored by Woolworths or Coles. All trademarks are the property of their respective owners.
