Category & Overall Rankings

In addition to individual keyword ranks, Cortex tracks real-time placements in App Store and Google Play top charts.

Tracked Charts

Cortex tracks three primary chart divisions across every supported store category:

1. Top Free: Most downloaded free applications within the last 24 hours.
2. Top Paid: Leading paid upfront application purchases.
3. Top Grossing: Applications generating the highest in-app purchase (IAP) and subscription volume.

Chart Movement Feeds

When an application jumps or drops significantly in ranking, Cortex generates an event in your activity feed:
