Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureFind discounts that leak margin before they cost you sales: a 90%-off code with no end date, a code still running months after the sale, or a quiet edit that widens a promo. GlitchGuard watches your discounts and alerts you in plain English, links each alert to the discount, and stays quiet about what you approve until it changes. It only reads discount data and never changes a discount.
A single pricing mistake can wipe out a week of margin. GuardUp catches it first. Every merchant has had it happen: a variant price drops from $99.00 to $9.90 because of a misplaced decimal. Or a 70% coupon goes live because someone typed an extra zero. GuardUp watches every price change and every discount in real time, surfaces the problem in your dashboard, and lets you fix it in one click.

- Get alerted when a discount changes from the setup you approved.
