A Brazilian price-tracking tool that reads an entire fiscal receipt from its QR code and compares what nearby shoppers actually paid.

Landing page captured for the 2026-09-01 issue.

Why it surfaced

Lupa builds its price data from NFC-e receipts and photographed shelf labels rather than manual submissions. It also totals the ICMS, PIS, and COFINS embedded in a purchase, while remaining an iPhone project in closed testing rather than a finished App Store release.
