Definition
The total number of public, marketplace-published reviews an app has received over its lifetime. Review count is a coarser signal than review velocity — a 10-year-old app with 50,000 reviews may have flat current momentum, while a 6-month-old app with 200 reviews could be growing rapidly. AppRanks displays both metrics on every app page so you can disambiguate. We diff successive snapshots to track velocity, and we flag anomalous drops (which usually mean the marketplace removed reviews flagged as fake). Review count includes only reviews still visible on the source marketplace at the most recent crawl — deleted reviews drop out of the count immediately on next refresh, no hidden cache. For comparing two apps in the same category, look at both the count AND the velocity; a high-count low-velocity app may be coasting on reputation that's eroding.

Why this metric matters
Review count is the most-cited public trust signal for marketplace apps but also the most easily misread. A high count alone doesn't mean the app is healthy today — it might be coasting on years-old reviews while current merchants churn quietly. Always pair count with velocity: a 50,000-review app with v90d of 5 is a different bet than a 200-review app with v90d of 80. For competitive analysis, count tells you historical scale; velocity tells you current direction; the ratio between them tells you whether the trend is positive, neutral, or eroding.
Use cases
- Quick competitive scan: in the same category, sorting by review count gives the historical leader; sorting by velocity gives the current-momentum leader; the gap between them is the disruption signal.
