What's New

A clearer download indicator, a finer speed dial, and a delete button that actually deletes.

• Tap a cover to cancel a download. Downloading books now show a large, App Store-style progress ring on the cover. Tap it to stop the download — no more digging through the context menu, and you can see exactly how far along each book is at a glance.
• Playback speed, your way. The speed pill on the player opens a full slider from 0.5× to 3× in 0.1 increments, with quick chips for 0.75×, 1×, 1.25×, 1.5×, and 2×. Dial in the exact pace you want for any narrator.
• "Remove from Library" sticks the first time. Deleting a book used to occasionally make it reappear because TorBox was serving cached data for a few seconds after the deletion. Spine now asks for a fresh read after every delete (and on pull-to-refresh), so the tile goes away and stays away.

And, the app now has a dedicated subreddit if you need support or have ideas for new features...

Just shipped an audiobook app and ended up leaning on the on-device Foundation Models framework for four things: "previously on…" recaps for series, cleaning messy filenames into typed structs, tightening publisher back-cover blurbs into 2-sentence summaries, and one-line witty captions for a year-in-review screen. All running on the 3B model, all offline, all free.

The real killer feature is @Generable + @Guide. You get a typed Swift struct back instead of parsing model output, and the per-field descriptions feel like a more reliable prompting surface than system prompts.

Rough edges: the safety classifier is aggressive on both input and output (book blurbs about war history or politics will trip it, permissiveContentTransformations plus stripping pull-quotes/URLs fixed most of it), and the model will confidently hallucinate authors for obscure titles, so treat output as a suggestion not truth.

Overall though: structured output, free inference, zero data leaving the device is a wild deal for a 3B model.
