Review momentum
61/100
faster than 69% of Utilities apps
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 Read Progre:Progress
This is a solar geometry training platform. Precise alignment is achieved using touch dials and sliders via quadrant, lunar illumination, noon analemma, station latitude, shadow rod, eclipse alignment, as well as azimuth, day length, twilight, declination, and angle-related questions. Each instrument comes with theoretical aids and formula explanations; completing the training unlocks the principle card and writes the observation log.
