Japanese dictionary and study apps

This cluster consists of Japanese dictionary and language-study apps, including offline and online dictionaries, keyboard utilities, and Anki-related tools. The dated entries span from 2009 to 2026 with sporadic release dates and no clear trend, though there is a small concentration in 2019 and a larger set in early 2026. Traction leaders are ReSearch, okonomi, and Sumire Japanese Keyboard Lite F-Droid, each with 0 stars.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
