Description by Carlos Castillo (from the App Store)

Shelfsound turns the MP3 audiobooks you already own into a beautiful, easy-to-use library.

ADD A BOOK IN SECONDS
Open a book's folder, select its MP3 files and cover image, and Shelfsound builds the book for you. Chapters are put in the right order automatically, so Chapter 2 comes before Chapter 10.

LISTEN YOUR WAY
• Skip back or forward 30 seconds
• Jump between chapters or pick one from the chapter list
• Playback speed from 0.5× to 3×
• Sleep timer: 5 to 60 minutes, or at the end of the chapter
• Lock-screen, headphone and notification controls
• Keeps playing in the background

ALWAYS PICKS UP WHERE YOU LEFT OFF
Shelfsound remembers your exact position and speed in every book. "Continue listening" puts your current book one tap away.

PRIVATE BY DESIGN
No accounts, no ads, no tracking. Your books and listening history never leave your phone.

Light and dark mode included.

Shelfsound plays audio files you provide; it does not sell or include audiobooks.
