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
