Methodology

How to read these signals

Counts are based on Shoplist's latest available public crawl signal dated March 31, 2026.

Shoplist has not yet found reliable public storefront evidence connecting a Shopify store to this app. This does not mean the app has no users. Some apps are new, admin-only, server-side, theme-independent, or otherwise difficult to detect from public storefront signals.

Merchant rows are filtered to public brand profiles with enough public data to link safely. Full workflow, filtering, and monitoring stay behind signup.

Review, pricing, feature, screenshot, and listing-change data come from public Shopify App Store and Shoplist crawl records. Signals can change between crawls.
