Multi-file audiobooks
Play every track in a book as one queue. Resume survives reload, new tabs, and other devices.
Your MP3s, M4B audiobooks, and lectures already live in Files. AudioCheck indexes the folders you choose, streams with live permission checks, and keeps a persistent player while you browse Nextcloud.
AudioCheck turns folders you already have into a clear library with a persistent player. Every stream and cover goes through live file permission checks — nothing is uploaded elsewhere.

An Android app connects to the open-source AudioCheck server app on your own Nextcloud. Stream or download your library — listening progress stays on your server. See licence & pricing below.
Browse your library and playlists, continue where you left off, download for offline listening, and control playback in the background. Sign in with Login Flow v2 — your main Nextcloud password is never stored in the app.
