Shrinkflation scanner powered by the shoppers it protects

Supermarkets are quietly robbing customers in plain sight. Orange juice shrank from 64 ounces to 59. Chip bags swelled with extra air while actual chips disappeared. Cereal boxes stretched taller and thinner to mask what's been taken away. Prices held steady — or crept higher. No company announces when a product gets smaller. It simply reappears on the shelf, looking familiar but delivering less. Households notice when groceries run out a day early and the budget arithmetic falls apart. ShrinkWatch transforms everyday shoppers into a crowdsourced surveillance system. Point your phone at a barcode while you're in the store. The app reveals the product's last shrink event, the magnitude of the change, and whether that brand has a pattern of doing this. That jar of peanut butter? It was quietly redesigned twice over eighteen months, getting lighter each time while the shelf price stayed put. Scan the toilet paper and learn the rolls shed twelve sheets last quarter behind packaging that looked exactly the same. Every single scan enriches the dataset. Begin with the basics. A barcode reader, a hundred high-profile products manually entered at launch, and a visual timeline tracking each product's shrinkage history. Users can photograph suspicious changes to flag them, expanding the database with every shopping trip. r/shrinkflation already boasts 192K members doing exactly this work through Reddit posts. They've been assembling this intelligence by hand for years. Hand them a proper instrument to formalize the effort. If they embrace it, the data snowballs rapidly. If they pass, the concept needs fundamental rethinking before anything else is worth pursuing. The consumer-facing app remains free because the entire model depends on data scale. $7.99 per month opens up the features that make scanning habit-forming: pre-trip notifications, rankings of which brands are downsizing most aggressively, and a cumulative tracker showing how much more families spend for diminished products. That's the consumer revenue stream. The bigger opportunity sits below the surface. Advocacy organizations pay for authenticated data they can present to regulators. Media companies and CPG brands pay a premium for access to the complete database. Using the app costs nothing. The intelligence it generates is another matter entirely.
