Seen on the storefront, not guessed
If Shoplist shows Wyllo on a store, it’s there. Every count on this page traces to code found on a live storefront, re-checked on every crawl.
4,956
Found in the storefront’s own code
Shoplist matches the scripts, app blocks and pixels Wyllo loads on each live storefront. No surveys, no developer-reported numbers, no model guessing installs from review counts.
48
Re-checked, so the count stays current
Shoplist keeps crawling the same storefronts. A store that uninstalls Wyllo leaves the count on the next crawl, so you read today’s install base, not a high-water mark.
Daily
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.
