I priced 30 items at three supermarkets with FieldPic Checklist. Here is what came out

Before launch day I wanted a real job for the app, not a demo. So I took one 30-item checklist to three supermarkets on National Route 17 in Saitama, just north of Tokyo, and photographed every price tag: 124 photos.

Each photo landed on its item as I took it. The three exports (a CSV and the photos each) went to Claude, which read the tags and converted the prices so they compare fairly: per potato, per 100g of coffee, per 2 fillets. The same jar of Nescafé Gold Blend 120g was ¥862 at one store and ¥1,295 at another.

The full comparison, with the photo behind every price: https://claude.ai/artifact/TaF1gfoAQNkMVHzdCjGDrm

A question for anyone who does site work: what list do you photograph today, and what does the report you hand over look like? I'd like to know which export would save you the most time.
