Pricing entry tiers: SMART Functions Creator at Free plan available, Singulary ‑ Merge Customers at Free plan available.

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.
