Mobile e-book reader apps

This cluster consists of mobile e-book reader apps that open local files in formats such as EPUB, PDF, TXT, FB2, and CHM, with many offering customization, bookmarks, and note-taking. Entries are dated from 2008 to 2026, with a sparse early history and a modest increase in entries from 2024 onward; the overall shape is a long, thin tail rather than a consistent flow. Traction is low overall, with shiori-local-reader leading at 2 stars, followed by Ebook-Apk-free at 1 star and EPUB Player at 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.
