Ebook reader apps

This cluster consists of ebook reader applications that support multiple document formats, OPDS catalogs, cloud storage integration, annotations, and customizable reading modes. The dated history is thin—only 4 dated entries exist—so the cluster's timeline shape cannot be determined. On traction activity, KyBook 3 Ebook Reader leads, followed by KyBook 2 Ebook Reader and KyBook - EPub,FB2,PDF,DjVu Reader.

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.
