What Sonnet does.
Read your way
Adjust reflowable text, choose a reading theme, and return to your saved position. PDF and comic controls reflect their page-based layouts.
Listen and learn
Play local MP3, M4A and M4B audiobooks with saved positions, speed and sleep controls. Use offline text-to-speech and the bundled English dictionary where text is available.
Keep what matters
Save bookmarks and notes, search your notebook, and export notes as Markdown or JSON.
Back up before changing devices
Export your library as a manual backup. Books and notes are stored locally; automatic cloud synchronization is not provided.
Find book sources
Open independent provider websites, download an available authorized book in your browser, then add the file to your local library.
Getting started
A few simple steps.
- 01
Start with a sample
Try a bundled original sample without creating an account.

Read, annotate and back up
Return to saved reading positions and export a backup before uninstalling or changing devices.
Where can I download Sonnet?
Download Sonnet for Android from Google Play or for iPhone and iPad from the App Store using the links on this page.
Which formats are included?
Sonnet includes EPUB, PDF, TXT, HTML, Markdown, FB2, unprotected MOBI/AZW/AZW3, CBZ/CBR comics, self-contained DjVu and MP3/M4A/M4B audio. Complex layouts, archive variants and device decoders have compatibility limits. Protected bookstore files and encrypted comic archives are unsupported.
Are my books uploaded?
Sonnet does not operate a book-upload or synchronization service. Sharing files or backups uses the destination you choose. Advertising, usage analytics and crash reporting can use an internet connection.
Does reading require an account or internet?
Local reading requires no Sonnet account. A cloud file provider may need internet to download a file before import. Ads, usage analytics and crash reporting are separate from local reading.
Can it unlock protected books?
No. Sonnet does not remove bookstore DRM. A password-protected PDF can be opened when you supply its password.
What should I send in a bug report?
Send the app and OS version, device model, file format, approximate file size and steps to reproduce. Retain the original and a backup. Remove private content from screenshots; do not email books or passwords unless you deliberately choose to share appropriate material.
