CLUSTER DOMAIN-LISTENING-PUBLIC · 5 ENTRIES · EARLIEST ENTRY 2025-01-12

Public domain audiobook apps

This cluster comprises apps for finding, streaming, downloading, and playing public domain audiobooks, with features like offline listening, bookmarks, and playback customization. The cluster's dated history before the index start consists of too few entries to read a shape from, so it predates the index or is undated. Traction is tied among Aradia: LibriVox listener, Libly: Audiobook Player, and ListenBook: audiobook player, 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.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
