Price Proof

Price Proof helps you catch the price mistakes stores make — when the shelf tag says one thing and the register charges another. Snap a photo of the price tag as you shop and Price Proof reads the price, stamps the time, and tags where you were. If it rings up higher at checkout, you have proof in your pocket.
Everything stays on your phone. No account, no sign-up, no ads, and nothing is uploaded to a server, your lists, photos, and prices never leave your device.
HOW IT WORKS

Build a shopping list, or just snap items as you go.
Photograph the shelf tag, Price Proof reads the price automatically; you confirm or fix it on a keypad.
Each item is saved with its photo, the time, and your location.
At checkout, watch the running total. If something's wrong, the proof is right there.
Finish a trip, attach the receipt, and save it.
