What this comparison measures.
What it measures
Shopify App Store ratings and review counts, rating distribution, developer reply rates, reviewer tenure and geography, listed pricing and capabilities, category data, and OngoingAI-observed storefront adoption for Aimerce First‑Party Pixel and Littledata.

Review growth compares the observed snapshots across the trailing 30-day window. “Stores observed” and the platform split come from OngoingAI’s weekly storefront census — the real stores running each app, not the listing’s claimed totals. Comparison generated Sep 16, 2026.
