The Chrome Web Store rounds user counts down to the leading digit, so the user line moves in steps. The ratings count is exact and is the better signal of real adoption.

About CartProof

CartProof helps Shopify agencies and freelance developers check storefront purchase-path readiness before client handoff. Run a non-payment QA audit from the current product page or a list of product URLs. CartProof checks Shopify storefront signals, product title and price, variant behavior, add-to-cart, cart state, discount handoff, checkout handoff, screenshots, console errors, and failed network requests. It then creates a printable client handoff report with evidence an agency can share before launch.
