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.

Great app. We tried out a bunch of others but this one gets the cake. Simple and quick to setup, free and responsive. What more could you ask for! It works great on our site and we set it up in no time. Thanks a lot!

    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.

    Find every brand running POWR.

    Ongoing.AI tracks every Shopify brand’s app stack daily. Pull the full install list, filter by vertical or geography, and catch the moment merchants install — or churn off.
