Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureYou know your store too well to shop it badly. An AI shopper opens it as a first-time customer, picks a product, and goes through checkout, recording what got in the way: a pop-up over the buy button, a card that will not open, a price that changes at the last step. Each run scores the experience and lists what it found. Our bot repeats the purchase every night and emails you if it's broken.
Show each batch's lab Certificate of Analysis on the product page, so shoppers can verify the exact lot before they buy. A badge opens the full certificate and a QR code looks up the lot. Forward a COA to a dedicated email or upload the PDF; AI reads lab, lot, dates, pass or fail and analytes with confidence scores, and you review before publishing. No shopper data is collected.
