Grocery Price Scanner
A grocery price scanner that runs on your phone
Shelf to Cart turns your phone camera into a grocery price scanner. Point it at a shelf price tag, confirm the item, and watch it land in a running cart total so you know what your trip will cost before checkout.
What a grocery price scanner does
A grocery price scanner reads the price the store is charging and adds it to your cart for you. Instead of typing every item, you scan the shelf tag and keep both hands on the cart. Shelf to Cart reads the item name and price, then keeps a running total as you move through the aisles.
It works as a grocery budget app for the moment that matters most: when you are still deciding what goes in the cart.
How the scanner reads shelf tags
Reads tags, not barcodes
Shelf to Cart reads the printed shelf price tag, so it captures the price the store is actually charging, including the tag on the shelf edge.
Handles sales and weighted items
Regular prices, sale tags, and per-pound or per-kilogram items are all supported, so the running total stays realistic.
Confirm or edit every item
Each scan shows the item and price before it is added, so you can correct a misread or adjust the quantity in a tap.
Scan, or add items by hand
When a tag is faded, angled, or missing, you can add the item manually with a name, price, and quantity. Scanning and manual entry feed the same running total, so a single shopping trip can mix both without breaking the math.
- Scan clearly printed shelf tags for the fastest entry.
- Add items manually when you already know the price.
- Edit any scanned price inline if the tag is wrong or out of date.
What to expect from accuracy
The scanner works best with clearly printed shelf tags and good lighting. Because you confirm each item before it is added, the running total reflects what you actually intend to buy. Shelf to Cart is a planning and tracking tool, so your store receipt remains the final record of the purchase.
Common questions
What is a grocery price scanner?
A grocery price scanner reads the price tag on a store shelf and turns it into a cart item. Shelf to Cart uses your phone camera to read the item name and price, then adds it to a running total so you can see what your trip will cost before checkout.
Do I need to scan barcodes?
No. Shelf to Cart reads the printed shelf price tag, not the product barcode. That means it works on the price the store is actually charging, including the tag taped to the shelf edge.
Can it scan sale tags and weighted items?
Yes. The scanner handles regular shelf prices, sale tags, and weighted items priced per pound or per kilogram. You can confirm or edit any result before it is added to your cart.
What happens if a tag is hard to scan?
You can add the item manually with a name, price, and quantity. Manual entry and scanning share the same running total, so you can mix both during a single shopping trip.
