PriceProof

PriceProof is a mobile + web app that turns everyday shopping receipts into a local, category-level “street price” index. Users scan or forward e-receipts; the app normalizes items (e.g., 2% milk, 1 gallon), removes obvious outliers, and shows price trends by store, neighborhood, and basket type (groceries, household staples, baby, pet). It’s built for people who feel prices rising but can’t tell what’s actually changing versus brand swaps, shrinkflation, or promos. The app also flags shrinkflation by tracking unit price changes and package size shifts over time. This is not a macroeconomic forecasting tool; it’s a practical, ground-truth tracker for personal budgeting and local reporting. Monetization is a subscription for advanced analytics and alerts, plus optional paid dashboards for local journalists and consumer advocacy groups.
