Based on the data on this page, Loox ‑ Product Reviews App is the stronger choice for most Shopify App Store merchants — 4.9★ vs Shopkeeper SizeChart's 0.0★ is a meaningful gap that usually reflects real product or support quality differences across the user base. Pricing entry tiers: Loox ‑ Product Reviews App at Free plan available, Shopkeeper SizeChart at Free plan available.

Loox ‑ Product Reviews App has the larger user base (8,222 reviews vs 0), which usually maps to broader integration coverage, faster bug-fix cadence, and a deeper bench of community workflow patterns.

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.

Great
Great app and even better support! I had an issue with the Reviews Widget not showing on my store because my custom domain wasn't recognized in the backend. 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
