Review momentum

faster than 0% of Reference 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 Dictionary of Japanese Names
CJKI's Japanese Names Dictionary is a based on the CJK Dictionary Institute's comprehensive collections of millions of Japanese names and their variants -- the largest such repository in existence.

In extreme cases, one kanji name can be pronounced 36 ways, whereas one romanized name can be written in more than 100 ways.
Q: Do you know how to read the name 一二三 and 海?
A: Kirara and Marin.
Q: Do you know to write in kanji the surname Hashizume?
A: Here some possibilities: 橋詰, 橋爪, 橋都 and 橋誥.

A: At least 168! Here are just a few: 明子, 晶子, 昭子, 彰子, 亜喜子, 亜希子, 安貴子 and many more.
