Got shorted? Prove it.
Weigh the package. Check the shelf tag’s math. Snap a photo. Shortchanged maps the stores where packages come up light and unit prices don’t add up, so shoppers, reporters and regulators can see the pattern.
Free. Nothing to install. No account needed.
What can you check?
Starting with groceries. Built to cover anything sold by weight, volume, count or unit price.
Three steps, one minute, right in the aisle.
Measure
Use the store’s produce scale or your own. Check your scale first: 10 US nickels weigh exactly 50 grams.
Snap
Get the label and the scale reading in one photo. For unit prices, shoot the whole shelf tag.
Post
Type in the numbers and we do the math. Your report is pinned to the store, other shoppers can confirm it, and you can turn it into a complaint for your state’s inspectors.
When the per-ounce math is wrong, the “better deal” isn’t.
Shelf tags show a unit price so you can compare brands and sizes. If a $6.00, 5 oz bag is tagged $1.00 per ounce, it looks cheaper than it is. The real price is $1.20 per ounce, 20% more than the tag says.
Enter the price, the size and the tag’s unit price. We check the math, even when the tag uses a different unit, like per pound for an item sold in ounces.

Post the first reportEvidence, not accusations.
Every report shows its photos and numbers and says how it was measured. Other shoppers can check the same item, and anyone can flag a report that looks wrong.
Photo proof
The label and the reading in the same shot. Location data is stripped from every photo.
Checked by others
Shoppers on other networks confirm or dispute a report. Store scales and calibrated scales are marked.
Fair to stores
Results say “short by at least,” never “fraud.” Stores will be able to reply to reports.
Every ounce counts.
Next time something feels light, check it. It takes a minute.
