ProKnockout:Background Changer downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.

In-app revenue
Worldwide, what users spend in ProKnockout:Background Changer before Apple and Google take their fee.
How this is calculated
Not in an overall Top Grossing chart, only in category charts: each category position is converted to the overall position it corresponds to, then priced on the same rank-to-revenue curve, inside the part of each market the charted apps leave over.

Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
