Pricing entry tiers: Loox ‑ Product Reviews App at Free plan available, DEVNZO Size Chart & Size Guide at Free plan available. Check each app's tier structure for the capacity limits you actually need before deciding — the headline number is the same shape, but the gating shape per tier (apps, orders, integrations) varies. Loox ‑ Product Reviews App has the larger user base (8,257 reviews vs 1), which usually maps to broader integration coverage, faster bug-fix cadence, and a deeper bench of community workflow patterns.

The data tables below show the per-feature breakdown — for most merchants the deciding factor will be a single integration or workflow detail that's hard to compare from listing pages alone. 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.
