Review momentum
ⓘ How we measure thisNew ratings a week
–
Google Play's rating count fell over the last 4 weeks: it removed more ratings than came in (spam clean-ups, deleted accounts), so the pace can't be read right now

Lifetime rating
3.8★
recent stars not readable yet: new ratings are a tiny share of the total
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.
