Read the press kit

SugarSpy home screen on iPhone. It reads: Find hidden sugar before you buy. Scan an item and compare sugar per 100 g with sugar per serving. Options include Smart Scan for a barcode or label, scanning a nutrition label only, and entering a barcode manually. A card notes that SugarSpy tracks 128 hidden sugar names with definitions.

SugarSpy started in a Chicago grocery aisle. Its creator, managing his own blood sugar, kept finding "0 g sugar" labels on products full of sweeteners under other names. He built the tool he needed: point your camera at any product and see the truth in seconds.
