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.

“KRAZY! That's all I can say. What a totally brilliant app. For a measly $10 our Pagespeed score went up >25%. How can you beat that? Try the app – you'll see. And then once you experience what we've experienced – continue to periodically rerun the app from time to time, to sort out changes that you make to your store. Possibly the best $10 investment ever!”

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.
