For iPhone & iPad · iOS 18 or later
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
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.
See the original PDF layout. Tap a paragraph to read its translation without changing the page.

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

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.
AI translation uses the surrounding text to help with expressions, tone, and specialist terms. You can compare any translation with the original.
Headers, footers, and page numbers are automatically omitted from translation. Crop wide margins with a single touch for an uncluttered reading view.
Use AI to retranslate a difficult passage, compare it with the original, or edit the wording yourself.
Translation Engines
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.
Translates on compatible devices with Apple Intelligence enabled and iOS or iPadOS 26 or later. Text stays on your device, and translation works offline.
Uses Gemini models to translate text, summarise chapters, and answer questions about your book. Requires an internet connection and Cloud credits.
An offline dictionary for all supported devices. Look up individual words while keeping the original sentence structure.
Audio Narration
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.
Use system voices or download neural voices for offline listening, including four Vietnamese voices.
Listen with the screen off. Check playback progress through Live Activities and the Dynamic Island.
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×.
Accompany your reading with rainfall, summer cicadas, soft jazz, or music from your Apple Music library, playing gently behind the narrator.

Privacy
No sign-up and no tracking of your reading. You decide when to share text with Flural Cloud.
Files are opened directly on your device. Text recognition and on-device translation run entirely on your iPhone or iPad.
No signup or profile required. Flural collects zero telemetry about what you read, when you read, or how long you spend.
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.
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.
