About Cartwise

Cartwise is building a crowdsourced grocery price map for everyday shoppers. The goal is simple: compare the same shopping basket across nearby supermarkets before deciding where to shop.

We plan to start with one city, three supermarkets, and a community of receipt contributors. Product matching, receipt verification, privacy protection, and clear timestamps are essential to making those comparisons trustworthy.

Help build your neighborhood’s price map.

Join early access to Cartwise. The app is in development, and local coverage will grow with community contributions.
