This verdict is generated from the live marketplace data on this page — rating, review count, pricing tier, and category position all refresh from the canonical Shopify App Store listing every 24 hours. AppRanks does not accept payment to influence comparison outcomes; the methodology is documented on the About page and applies identically to every pair on the site.

Liz from the support team was quick, professional, and resolved it within minutes by resyncing my widget cache. Really appreciate the fast and effective help — hig
