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 AlertaBlu
ALERTABLU is the official app of the Blumenau Civil Defense and provides real-time information about the Itajaí-Açu River, rainfall, and weather conditions in the city.

When the river level reaches higher levels, the app also provides level forecasts for the next hour, helping to monitor the evolution of floods.
