Made for long listens

Everything the story needs. Nothing it doesn’t.

Sliver treats an audiobook like an audiobook—not a long song. Chapters, progress, speed, silence skipping, and sleep timers are all built into the listening flow.

01 · Your library

Point to a folder. Sliver does the rest.

Titles, authors, artwork, duration, and chapters are read directly from your M4B files.

02 · Fine-tuned

Listen your way.

Set per-book speed, skip silence, choose your jump intervals, and drift off with a gentle sleep-timer fade.

03 · Google Cast

Send the chapter to the room.

Cast the current audiobook and position to a receiver while chapter navigation and playback controls stay on your phone.

04 · On your wrist

Standalone playback on your watch.

Choose chapters from your own M4B files, transfer them to Wear OS, and play them directly on the watch—with dedicated controls and saved progress.
