Where the numbers come from.

Ratings, review counts, pricing tiers, “Built for Shopify”, launch date, and category memberships come from the live Shopify App Store listing — refreshed daily by Ongoing.AI’s crawler. The review-count trajectory is the diff between today’s snapshot and snapshots from 7 and 28 days ago. Topic counts and sentiment come from the review corpus, topic-tagged with Claude. Install footprint is observed via Ongoing.AI’s tech-detection pass against actively-tracked Shopify storefronts. Catalog position is computed at snapshot time against every active app sharing the primary category. Snapshot generated .
