iRead is a calm reader for people learning a language through real texts. Bring in a book, an article or a PDF in the language you're learning, read at your own pace, translate unfamiliar words with a tap, and keep them in a personal vocabulary. READ ANYTHING - Books in FB2 (including fb2.zip), EPUB and TXT β€” with the author, italics and bold preserved - Articles and notes in Markdown - PDFs: select text right on the page and translate it. Each PDF remembers its language pair, the page and the zoom you left it at - Pages of paper books: take a photo and the text is recognized automatically - Pasted text and anything shared from other apps TRANSLATION WITHOUT THE INTERNET - Translation runs on your device β€” fast and private - Any pair of system-supported languages: you choose what you read and what you translate into - Language packs download once; after that everything works offline YOUR READING DAY - The Library opens with your day: how long you read and how many words you saved - A reading diary: each day shows the time you spent, the books you read and the words you kept - Reading rhythm: a gentle plan for each language β€” say, English on weekdays, 20 minutes. See it fill up in Today and across the week, with an optional reminder that opens the book you're reading. No streaks A PERSONAL VOCABULARY, WITH REVIEW - Save words and phrases together with the sentence you found them in - Categories, favorites and search - Review that goes through your whole vocabulary: every word comes up in turn, and the ones you missed come back a little sooner - Short sessions of up to ten words for each language β€” you only ever answer "Knew it" or "Didn't know" - Fresh words: what you saved in the last few days gets its own short session, all your languages together - An optional reminder the morning after you save words, at a time you choose - Hard words show how many times you didn't remember each one - Quiet statistics, no streaks - Saved words are gently underlined as you read, so what you've learned shows up in the text itself - Word hints: the translation of words you're still learning can appear right above them in the text, and disappears once you know the word COMFORTABLE READING - Book-style typesetting: justified text, chapter headings, and hyphenation that follows the language of the book - Page breaks: a quiet line about once a screen gives long chapters a rhythm - Six themes: four warm paper tones, a clean White, and E-reader β€” a calm gray screen with its own book typeface, Literata β€” plus a dark mode - Seven text sizes on top of the system setting - Tapping a book picks up right where you left off β€” straight to your last chapter, with the contents one swipe back - Reading Now keeps started books close at hand - In the PDF reader the page lies on paper, and one tap hides the panels ON IPAD - Translation appears in a small popover right next to the word, so the page stays readable around it - Your library, vocabulary and settings sit in a comfortable reading column on a large screen - PDFs in landscape fill the width of the screen and stay sharp; turning the iPad keeps your place SYNC AND PRIVACY - Your library and vocabulary sync across your devices through iCloud - Data lives in your private iCloud database; translation never leaves the device - No accounts, no ads, no tracking

About

FlowLingua

Features
Read full description

Other apps make you click. We let you read. FlowLingua is a bilingual reader that turns any foreign-language book into a bilingual book. Import your own books, articles, videos and audio β€” or start with the ready-made content in the library. Read and listen to foreign-language content as if it were your native language. Every word and every sentence is already translated β€” synced to the audio, with no clicking at all. No dictionary, no vocabulary drills, no loss of flow. It is the digital heir of the interlinear tradition β€” the bilingual books and parallel-text editions of Ilya Frank, but without the page flipping, and for any book you choose. β–Έ WHAT FLOWLINGUA DOES β€’ Automatic bilingual reading β€” the Birkenbihl method in its purest form: every word of your book sits right under the original, including grammatical structure. β€’ Translated sentence by sentence β€” plus the natural sentence translation, so nothing stays unclear. β€’ Synced to the audio β€” text and original audio run word by word together (karaoke principle). You train pronunciation, rhythm and listening comprehension. β€’ Import your own content β€” EPUB, PDF, DOCX, YouTube videos and audio files are decoded and translated automatically. β€’ Easy reading β€” a dedicated Birkenbihl mode for relaxed, uninterrupted reading. β€’ Vocabulary tracking β€” unknown words come pre-marked; you remove the mark once you know them. β€’ Shadowing & speaking practice β€” repeat sentences right after native speakers, with sentence repeat. β€’ Learn offline β€” download content and keep learning anywhere. Progress syncs automatically. β€’ 20 languages β€” from English, Spanish and French to less common languages. β€’ Listening-Reading (L-R) without the three-window setup β€” one screen. β–Έ HOW IT WORKS 1. Import β€” bring your own book, video or audio, or pick ready-made content. 2. Understand β€” everything is already translated, word by word and sentence by sentence. 3. Stay in flow β€” press play and let the audio guide you. The translation is there when you need it. β–Έ WHO IS THIS FOR? β€’ You want the books you actually care about as bilingual books β€” without flipping pages or clicking every word. β€’ You want to read foreign-language books and understand them right away. β€’ You know the Birkenbihl method and finally want a tool that decodes automatically. β€’ You come from a reader where you have to click every single word β€” and you're done with the clicking. β€’ You've drilled vocabulary and still never understood a real book. β–Έ WHY FLOWLINGUA EXISTS I wanted to learn languages β€” but memorizing vocabulary and grammar put me off. So I researched how polyglots really do it: understand, don't memorize. That's why I built FlowLingua as an app. FlowLingua combines three proven input methods: the Birkenbihl method (decoding), Listening-Reading (listening and reading at the same time) and Comprehensible Input by Stephen Krashen (understandable content that interests you). β–Έ SUPPORTED FORMATS EPUB Β· PDF Β· DOCX Β· YouTube Β· MP3 & audio files β–Έ FREQUENTLY ASKED QUESTIONS Can I use FlowLingua as a bilingual book reader? Yes β€” import any EPUB, PDF, video or audio file and FlowLingua turns it into a bilingual book: original and translation together, word by word and sentence by sentence, synced to the audio. The library also has ready-made content to start with. Do I need prior knowledge? No. The word-for-word translation makes texts understandable even if you don't know a single word yet. How is this different from vocabulary apps? You learn with real books, videos and audio β€” not quiz exercises. Understanding comes first. Does it work offline? Yes, content can be downloaded. Stay in flow. Not in the dictionary. 7-day free trial. β–Έ ATTRIBUTION Sample content β€œDaily Routine”: work by SpeakSmart Academy, licensed under CC BY 4.0 (creativecommons.org/licenses/by/4.0/).
