A calm, focused audiobook player for two libraries: thousands of free public-domain classics from LibriVox, and the audiobook files you already own. No subscription. No ads. No noise. Read every classic ever written. For free. LibriVox volunteers have recorded thousands of public-domain books — Pride and Prejudice, Sherlock Holmes, Crime and Punishment, Dracula, The Great Gatsby, the complete works of Dickens, Austen, Tolstoy, Twain, Verne, Doyle, and many more. Browse by popularity, search by title or author, and start listening in a tap. Chapters stream on demand — no need to download an entire book before you press play. Bring your own audiobooks. Got an .m4b you bought years ago, or a folder of .mp3 chapters from a backup? Drop them into libFT through the iOS Files app and they appear in your Library, organized by folder, with embedded cover art and natural chapter ordering preserved. Your files stay on your device — they aren't uploaded anywhere. One player. Two libraries. One place you left off. Continue Listening picks up where you stopped — whether the last chapter was a streamed LibriVox novel or a local audiobook from your own collection. Favorites, playback speed, lock-screen controls, background playback through headphones, AirPlay, and car audio all work the same across both sources. Built for long listens. - Continue Listening across both libraries - Favorites for the books you'll come back to - Variable playback speed - Lock Screen and Control Center transport controls - Background playback through headphones, AirPlay, and car audio - Auto-pause when you unplug headphones - Clean resume after phone calls - Available in English, German, Spanish, French, Portuguese, and Ukrainian No subscription. Ever. LibriVox audiobooks are recorded by volunteers and released into the public domain — they cost nothing to listen to. libFT itself is free to use. The audiobook files you already own stay yours, on your device. No tracking, no ads, no monthly fee. About LibriVox. LibriVox is a volunteer-driven project that records audio versions of public-domain books in many languages. libFT streams those recordings through the Internet Archive (archive.org). Special thanks to the thousands of LibriVox volunteers whose voices make this catalog possible.

Verdict

The call

The clearest difference is in-app purchases: libFT at none against Book AI's 1. libFT also leads on ads (none vs shown) and rating (5.0 vs 4.6). Book AI's advantage is ratings volume (101 vs 2). On price, update cadence, device support and iOS requirement there is nothing between them.
