CartSwap finds a cheaper, similar version of the groceries you already buy at Walmart, so you spend less on every trip. If something isn't working or you have a question, reach out and we'll get back to you.
As you build your cart, CartSwap looks for a cheaper, similar version of each item — and shows you exactly how much you'd save. When you're ready, send your optimized cart to the Walmart app to check out.
Sometimes the item you picked is already the cheapest good option. When there's no cheaper match, we tell you honestly rather than suggesting a worse product.
Point your camera at a product's barcode while you shop and CartSwap checks for a cheaper swap on the shelf. Camera images are processed on your device to read the barcode — they aren't stored or uploaded.
CartSwap Pro unlocks unlimited swap reveals and full savings tracking. It's an auto-renewing subscription billed through your Apple Account.
Subscriptions are managed by Apple. On your iPhone, open Settings → [your name] → Subscriptions, select CartSwap, and choose to change or cancel your plan. Cancel at least 24 hours before your renewal date to avoid the next charge.
Open CartSwap, go to the upgrade screen, and tap Restore Purchases. Make sure you're signed in with the same Apple Account you used to subscribe.
CartSwap requires no account, and your cart, favorites, and savings history stay on your device. Read our Privacy Policy for details.
