Seriously loving the app

“Hello, seriously LOVING the app! I am wondering where quotes are stored?”

marksewellApp Store

Just what I needed!

“I’ve tried BookPlayer, Bound, and Apple Books. HushBook is the first app that correctly displays chapter elapsed and remaining time on my 2017 Toyota Camry JBL head unit, the steering wheel controls change chapters correctly, and the on-device transcription is excellent. Thank you!”

u/larryloveinsteinReddit

Made for daily reading

“Hello! I have it downloaded and very cool app. Is there a way to increase playback speed? I find that’s the only thing from incorporating this into my daily reading.”

Brilliant app for staying focused!

“I love the on-device transcription and the specialized reading modes (the dyslexia font and high-contrast layouts are fantastic). Highly recommended!”

Wilhelm DrescherGoogle Play

“Perfect app just what I wanted. Pro unlocks more stats as far as I can see.”

Dennis BransonGoogle Play

“Great app! Could you please add option to highlight the current sentence and not word, cause ai makes words bold either too slow or too fast, so they are not synched with speech. Ability to add whole book without choosing chapters 1 by 1 would also be nice for multiple files 👍”

u/Temporary_RelevantReddit

Deserves five stars

“I just downloaded it. It deserves really 5 stars! Good work”

Transcribed on your phone. Never the cloud.

✓No account, no sign-in. Open the app and start reading.
✓Fully offline after a one-time engine download — on a flight, in a tunnel, anywhere.
✓Thermal-aware. Long books transcribe in chunks, resume on failure, and keep your phone cool.

The free audiobook app

Free audiobook app with synced texts

Read every word as you hear it — the read-along player built for focus, privacy, and books you already own.

Looking for a free audiobook app with synced texts? HushBook is built for people who want more than plain playback. Ordinary players stream narration and leave your eyes with nothing to follow. HushBook turns listening into audiobook with words: every spoken word lights up in time with the narrator, so you read along the way lyrics move in a music app — only this time, the track is a full book.

Why synced text beats listening alone

Passive audio is easy to start and easy to lose. Minds drift. Names blur. You finish a chapter and realize you retained almost nothing. Word-level highlighting anchors attention to the voice: you see what you hear, seek any line with a tap, and keep place without rewinding half a chapter. That dual-channel focus is why many readers call HushBook one of the best free audiobook apps when comprehension matters as much as convenience.

Best audiobook apps — what actually sets HushBook apart

Search “best audiobook apps” and you’ll find storefronts, subscriptions, and cloud libraries. Apple audiobooks, including Apple Books audiobooks, Audible audiobooks, and YouTube audiobooks can help you discover a title; each has its own catalogue, terms, and availability. Search phrasing varies too: someone looking for “audiobooks Apple” is usually comparing the same Apple Books catalogue. HushBook solves a different problem: how you read the audio you already have. Import your own MP3, M4B, FLAC, and more; chapters and cover art come along when the file includes them. Tap Transcribe, and the on-device HushBook Engine builds synchronized text — no lyrics database, no upload, no account. After a one-time engine download, the whole experience works offline. That private, file-first design is rare among mainstream audiobook apps for iPhone and audiobook apps for Android.

Where to find free audiobooks on iPhone and Android

Wondering where to find free audiobooks? Start with the public-domain library in HushBook, featuring classics from LibriVox and the Internet Archive that you can browse and download. It is a free audiobooks app for iPhone and Android, with no ads in the core experience: listen to audiobooks for free, read along, save quotes, and play offline. For free audiobooks online, check the source and rights before downloading. If you are comparing an audiobooks subscription or an audiobooks free trial, use it to discover paid catalogues; HushBook remains free for the books you already own and the public-domain titles you choose. Whether you need audiobooks iPhone users can follow word by word on a commute or an Android player for bedtime listening, the promise stays the same: private by design, synced text included.

Your books — from classics to a Project Hail Mary audiobook

Lists of the best audiobooks 2026, best audiobooks 2025, and top audiobooks are a useful starting point, but the right pick is personal. Bring the titles you care about: thriller audiobooks for a late-night walk, fantasy audiobooks for a long trip, romance audiobooks for a quiet evening, or audiobooks for kids for a family car ride. If you buy audiobooks elsewhere, import a Project Hail Mary audiobook file you already own (or any other book you have rights to play), run transcription on your phone, and follow Ryland Grace word by word. Prefer public-domain epics? Start with Monte Cristo, Austen, or Aurelius from the built-in catalogue. HushBook is not a piracy storefront — it is a player and read-along engine for files and free classics you choose. Synced text works across languages too: the engine supports dozens of tongues so an audiobook with words can match the language you hear.

Privacy, accessibility, and habits that stick

Transcription never leaves the device. There is no sign-in wall and no cloud for your audio. Reading profiles reshape the whole UI for comprehension, dyslexia/ADHD, or low vision — fonts like OpenDyslexic and Atkinson Hyperlegible, overlays, contrast, and night mode included. Streaks, badges, and gentle stats stay local, so habit-building does not require a surveillance stack. That combination — free core, synced text, on-device AI, accessibility — is why HushBook ranks among the strongest answers when people search for the best free audiobook app that respects both focus and privacy.

Ready to read along? Download HushBook free for iPhone or Android, pick a free classic or import a book you own, and watch every word light up with the voice.

Questions?

Answers.

No. Transcription runs entirely on your device — there's no upload, no account, and no server. After a one-time engine download, the whole app works offline.

HushBook generates them from your audio with the on-device HushBook Engine — there's no lyrics database. The first pass on a long book takes a while; after that, it's instant every time you open it.

MP3, M4A, M4B, AAC, WAV, FLAC, OGG, OPUS, OGA, AIFF, AIF, MKA, and ALAC — one file per import. Chapters inside M4B files are detected automatically, along with cover art and metadata.

The core read-along experience and the public-domain library are free. There's an optional Pro upgrade for advanced analytics — going Pro helps keep HushBook independent and improving.

The Engine is thermal-aware: it caps its worker threads and rests between chunks to keep your phone cool, and it resumes automatically if a long transcription is interrupted.

Anyone who reads with their ears — and especially readers with dyslexia, ADHD, or low vision, language learners, and anyone who focuses better when they can see the words they hear.

Yes — night mode swaps the blurred cover backdrop for a solid dark canvas, and the Vision profile adds high-contrast themes like white-on-black and amber-on-black.

Yes. HushBook highlights every spoken word in sync, so you can read and listen at once without losing your place.

Most audiobook players do not. HushBook generates word-synced text from your audio on your phone, so you can follow the narration without a separate transcript or ebook.

No. You do not need a Kindle, ebook, or second purchase. Import audio you own, and HushBook creates the synchronized text on your device.

Whispersync and Immersion Reading usually depend on Audible plus a matching Kindle ebook. HushBook works with your own audio files, generates text privately on your phone, and does not require an Amazon account or cloud upload. Compare library, bookstore, and owned-file options in the Audible alternatives guide.

Many listeners find that seeing and hearing the same words keeps attention anchored and makes it easier to retain a chapter than audio alone.

Yes. Word-level highlighting and reading profiles support dyslexia, ADHD, low vision, language learning, and anyone who focuses better when they can see the words they hear.

Yes. After the one-time HushBook Engine download, playback, read-along, and transcription run on your device without an internet connection.
