SodaSwap
SodaSwap helps shoppers cut soda costs without gambling on random off-brands. You scan a barcode (or search) and the app suggests close taste-profile alternatives available at nearby stores, ranked by similarity and price-per-ounce. It also flags hidden shrinkflation by tracking package size changes over time, so you can see when your “usual” quietly got smaller or pricier. Users can set a target budget (weekly/monthly) and get alerts when a preferred brand drops below a price threshold. The app is realistic about data quality: it won’t magically know every store’s price, so it focuses on the retailers you connect (digital receipts, loyalty accounts) plus user-submitted price checks with confidence scores. Over time, the database gets better, and power users can contribute verified prices to unlock premium features.
