Shopify stores using AddOnce
Shoplist is watching Shopify storefronts for the first public install of AddOnce.
How AddOnce’s install base is moving
Shoplist re-crawls the same storefronts, so every store that adds AddOnce, comes back to it or removes it shows up here. The store count also grows when Shoplist finds stores already running it; the breakdown keeps those apart from real installs.

Seen on the storefront, not guessed
If Shoplist shows AddOnce on a store, it’s there. Every count on this page traces to code found on a live storefront, re-checked on every crawl.
Code-level
Found in the storefront’s own code
Shoplist matches the scripts, app blocks and pixels AddOnce loads on each live storefront. No surveys, no developer-reported numbers, no model guessing installs from review counts.
Re-checked, so the count stays current
Shoplist keeps crawling the same storefronts. A store that uninstalls AddOnce 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.
