Psst

Psst is a shared shopping list app for iOS and Android that remembers what items cost. Users can photograph a receipt and the app returns structured line items, each showing a crop of the original row, what the item cost last time, and where. It emphasizes caution with uncertain data: prices in different units are never compared, and comparisons are made on unit price rather than line total. Psst also offers real-time shared lists with chat, a Today view, and plain-language quick-add.

Psst shows how a narrow, everyday problem—remembering what groceries cost—can be solved with careful, opinionated design. Its emphasis on accuracy over confident guesses and its unit-price-aware comparisons offer a useful model for startups building data-extraction or tracking features where trust matters more than flashy output.
