Review momentum
ⓘ How we measure thisReview 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 Old Japanese Clock
The fixed hour system includes six different types: Engishiki, Guchureki, Semmyoreki, Semi-Engishiki, Kanagoyomi, and Shichiyoreki. These systems were primarily used from the Nara era through to the Edo era (c. 710–1872).
On the other hand, the temporal hour system encompasses seven types: Temporeki, Koten, Shaku-Sun-Bu (Class 1 and 2), and Three-Divided (Class 1 to 3). These were predominantly used during the late Edo era (1844–1872).
This app proves invaluable when reading Japanese historical documents, adjusting Japanese clocks (Wadokei), or recreating the lifestyle of ninjas and samurais, among other apps. For more detailed information, please visit the developer's website.
