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.

“Paul is unbelievable. The app wasn't exactly what I needed (for now) but he took the time to send me a detailed e-mail to try to help me out. Just fantastic customer service and a sign that he is truly invested in this app. You don't see that much these days!”
“While it says "Find" and merge duplicate accounts, there is not yet any service with which to find them - it does not suggest Doppelganger accounts for merging, you need to already know which accounts you want to merge. I understand this is in development (and not easy!) so I look forward to testing the new app.”

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.
