Description
HushBook is a free audiobook app designed to provide a unique reading experience by offering synced texts that allow users to read along with the audio. Available on both iPhone and Android, HushBook turns any audiobook into a word-level karaoke experience, enabling users to follow along as each word lights up in sync with the narration.
The app operates entirely on-device, ensuring that users' audio files and transcriptions remain private. There is no need for an account or cloud storage, making it a convenient choice for those who value their privacy. After a one-time download of the HushBook Engine, users can enjoy offline playback, making it suitable for use in various environments, such as during commutes or in areas without internet access.
HushBook supports a wide range of audio file formats, including MP3, M4A, M4B, AAC, WAV, FLAC, OGG, and more. Users can easily import their own audiobooks and the app will automatically detect chapters, cover art, and metadata. The core features of HushBook include accessibility reading profiles tailored for users with dyslexia, ADHD, or low vision, ensuring that the app is inclusive and user-friendly.
The app also includes a public-domain library, allowing users to browse and download free classics from sources like LibriVox and the Internet Archive. HushBook is not just about listening; it encourages active engagement with the text, which can enhance focus and comprehension. Many users find that seeing and hearing the same words helps them retain information better than audio alone.
For those looking for deeper insights into their reading habits, HushBook offers an optional Pro upgrade that unlocks advanced analytics. This feature provides users with a brain score based on their reading streaks, words read, and comprehension levels, helping them track their progress over time. HushBook is built for anyone who enjoys audiobooks and wants to enhance their reading experience through synchronized text.
