Review trajectory.
Daily review count and rating drift. The blue line is cumulative review count; the dashed amber overlay is the rating on the right axis. Boring is good — sudden swings stand out against an otherwise stable curve.

Methodology
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 Jun 12, 2026.
