Seen on the storefront, not guessed

If Shoplist shows PO Box Blocker on a store, it’s there. Every count on this page traces to code found on a live storefront, re-checked on every crawl.

  1. Code-level

    detection on every store

    Found in the storefront’s own code

    Shoplist matches the scripts, app blocks and pixels PO Box Blocker loads on each live storefront. No surveys, no developer-reported numbers, no model guessing installs from review counts.

  2. last checked

    Re-checked, so the count stays current

    Shoplist keeps crawling the same storefronts. A store that uninstalls PO Box Blocker leaves the count on the next crawl, so you read today’s install base, not a high-water mark.

  3. Daily

    App Store listing reads

    The App Store, read every day

    Rank, reviews, pricing and every listing edit are captured daily, so a price change or a ranking slip shows up here the day it ships.

Two public sources, labelled on every section. Store data last checked .
