Prologue

Somewhere, in a language you cannot read, someone wrote down what you have been looking for. Flural opens that book in the language you think in — and when your eyes are tired, reads it to you.

The Page

Keep the original page. Read in your own language.

Read a PDF in its original layout or switch to a single column of translated text. You can always return to the original to check a passage or illustration.

  1. Original

    See the original PDF layout. Tap a paragraph to read its translation without changing the page.

    Flural — Original
  2. Flow

    Read translated text in a single column. Long-press a paragraph to check the original.

    Flural — Flow
  3. Read ahead

    Flural translates upcoming pages while you read. Translation continues while you use the app and while background audio is playing; it pauses when iOS suspends the app.

  • Context & tone

    AI translation uses the surrounding text to help with expressions, tone, and specialist terms. You can compare any translation with the original.

  • Clean Margins

    Headers, footers, and page numbers are automatically omitted from translation. Crop wide margins with a single touch for an uncluttered reading view.

  • Adjust your translations

    Use AI to retranslate a difficult passage, compare it with the original, or edit the wording yourself.

Translation Engines

The right translation engine for every book.

Supports 10 languages: English, Vietnamese, Chinese, Japanese, Korean, French, German, Spanish, Italian, and Thai. Assign different engines and target languages independently to each book in your library.

    An offline dictionary for all supported devices. Look up individual words while keeping the original sentence structure.

Audio Narration

Close your eyes. The story continues.

Listen to the original text or its translation. Pick up where you left off and give your eyes a break.

A book can carry a voice across centuries and continents.

With a voice to read it aloud, the same page becomes something you can listen to.

Even with your eyes closed, the story continues.

  • Natural voices

    Use system voices or download neural voices for offline listening, including four Vietnamese voices.

  • Background Listening

    Listen with the screen off. Check playback progress through Live Activities and the Dynamic Island.

  • Sleep Timer

    Stop playback at the end of a chapter or after 15, 30, or 60 minutes. Adjust the reading speed from 0.75× to 2.0×.

  • Ambient Soundtracks

    Accompany your reading with rainfall, summer cicadas, soft jazz, or music from your Apple Music library, playing gently behind the narrator.

Privacy

What you read belongs only to you.

No sign-up and no tracking of your reading. You decide when to share text with Flural Cloud.

  1. Documents Stay on Your Device

    Files are opened directly on your device. Text recognition and on-device translation run entirely on your iPhone or iPad.

  2. No Accounts, No Tracking

    No signup or profile required. Flural collects zero telemetry about what you read, when you read, or how long you spend.

  3. Online Only When You Ask

    Text is sent online only when you choose Flural Cloud for a book and agree to share it. You can withdraw that permission in the app.

  4. Your text is not stored by Flural

    Flural does not store or log the text sent to Flural Cloud. Google processes it under its paid API terms and may retain it temporarily for abuse monitoring. See the privacy policy for details.

Transparency

    Flural opens PDFs and EPUBs without DRM protection. It cannot open DRM-protected books, including protected titles from Kindle, Google Play, or Kobo, and does not remove DRM.

  2. Translations can make mistakes

    Translation and text recognition can make mistakes. Check the original whenever a passage seems unclear.

  3. Device requirements
