Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureOfferproof is a read-only monitor for your discounts. It scans on demand with Scan now, or every day, and checks for app-created discounts with no end date, codes near their usage limit or redeemed far above usual, codes the same customer can reuse, automatic discounts that combine with each other, and a discount or combination that prices a variant at zero. Each finding names the discount and the setting to review.
Review Shopify discount definitions from a read-only dashboard. StackLens highlights overlapping campaign windows, combination-setting signals, upcoming starts and expirations, reported code-usage limits, and automatic-discount capacity. Each finding shows observed evidence and limitations. It doesn't edit discounts or predict which discount will apply to a cart.
