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.

About Adaptivity (A)
Adaptivity is an invaluable tool for developers and designers. Use it to visualize how Size Classes and margins for layout, readable content and the safe area look on real devices and how they change with respect to orientation, iPad multitasking and Dynamic Type size changes. A comprehensive System Images browser shows the different SF Symbols data sets across iOS versions with availability, localization and name change information. There are also views for visualizing Dynamic Type styles, System Colors, System Fonts and System Materials.
