Smarter Audio Player

Smarter Audio Player is a modern audiobook and long-form audio player for Android. Add each of your storage sources once — a folder on this device, a NAS share, a WebDAV or SFTP/FTP server, or a Google Drive account — and the app builds one clean library from all of them. Browse, scan, and stream everything through a single player, with per-book playback speed, bookmarks, a sleep timer, and playback-position resume across every source.

ONE LIBRARY, EVERY SOURCE
• This device — pick any folder on internal storage, an SD card, or a USB drive via Android's Storage Access Framework. No broad-storage permission needed.
• SMB / CIFS — Windows shares, UGREEN, Synology, TrueNAS, and most consumer NAS boxes.
• WebDAV — Nextcloud, Synology, UGREEN Cloud, or any PROPFIND-compliant server.
• SFTP — trust-on-first-use host key pinning, ssh-style, so a changed key is refused.
• FTP — commons-net with random-access reads.
• Google Drive — sign in with your Google account and browse your Drive folders.

BUILT FOR LONG-FORM AUDIO
• Bookshelf sorted by New / Started / Finished with per-book progress.
• Bookmarks with optional notes; jump back to any spot in any book.
• Per-book playback speed, skip-silence, volume boost, rewind-on-resume.
• Sleep timer that keeps running when the screen is closed.
• Chapter/track list for every book.
• On-device chunk cache so seeks are instant once a region has been played.
• Lock-screen and notification playback controls; Android Auto compatible.

PRIVATE BY DEFAULT
• No accounts, no analytics, no advertising, no third-party trackers.
• Passwords and OAuth refresh tokens are stored using Android's EncryptedSharedPreferences, encrypted with a key held in the Android Keystore.
• Cleartext HTTP is permitted only because most home NAS boxes serve WebDAV over plain HTTP on the LAN — internet traffic to real hostnames still goes over HTTPS.
• Google Drive access uses the drive.readonly scope only. The app has no write, share, or delete permission.

FREE AND PRO
The core player and local phone-files source are free forever. Network sources (SMB, WebDAV, SFTP, FTP, Google Drive), bookmarks and playback statistics unlock with a single one-off purchase — no subscription.
