Do I need the extension to use the web app?

No. You need a FlixFluent account and subscription. The extension adds dual subtitles and quizzes on Netflix and YouTube; the web app is where you review, practise and track your level.

Does the web app work on my phone?

Yes. Flashcards, the Trainer, tests, My Dictionary, the catalogue and Settings work in phone browsers, and you can install the app to your home screen as "FlixFluent Web". Watching with FlixFluent needs the extension on a computer.

What counts as study time?

Minutes in which you hover words, open explanations or sentence breakdowns, review flashcards, answer quiz questions or take a placement test. Gaps of up to four minutes are bridged; watching without interacting does not count.

Why is my study time lower than my watch time?

Because only active learning counts. Minutes where you only watch, without hovering, clicking, reviewing or answering, are not study time.

What is the difference between Flashcards and the Trainer?

Flashcards are FSRS-scheduled reviews of individual words you looked up. The Trainer replays the quiz questions from videos you watched, line by line, with a link back to each scene.

Can teachers see their students' progress?

Yes, with a school account. Students who join with the school's code appear on the Students page with their activity, study time, words looked up, flashcard reviews and quiz results. Email mail@flixfluent.com to set one up.

Is there a native mobile app?

A native iPhone and Android app is in testing and not yet available in the app stores. The web app already works in mobile browsers.

The FlixFluent web app (app.flixfluent.com)

The FlixFluent web app at app.flixfluent.com is the part of FlixFluent that does not need the browser extension. It holds Flashcards (FSRS spaced repetition built from the words you looked up), the Trainer (practice for your video-quiz questions), the catalogue of videos rated A1–C2, placement tests, My Dictionary with Anki and CSV import, and your study time. It runs in any modern browser, including on phones, and can be installed to the home screen as "FlixFluent Web". Watching with dual subtitles still happens in the extension on a computer. Teachers with a school account also get a Students page.

What is in the web app?

Everything around watching: reviewing, practising, measuring your level and choosing what to watch next.

Dashboard: your study time, your CEFR level and shortcuts to every section, plus setup help when the extension is not installed yet. Catalogue: Netflix and YouTube titles watched by the community, each rated A1–C2 and filtered to your level (see /catalogue/). Flashcards: the FSRS deck built from the words you looked up while watching, with optional typed or multiple-choice answers and pronunciation audio (see /vocabulary-trainer/); Add vocabulary can also suggest words from a show you watched or a topic you type, pitched to your tested level.

Trainer: every video-quiz question you have seen, to practise by video or as a mixed session, with the line read aloud and a link back to the scene (see /video-quizzes/). Proficiency tests: 20-question CEFR placement tests in nine languages that take 5 minutes at most. My Dictionary: every saved word with its review state, search, Anki (.apkg) and CSV import, CSV export, and your ignored words.

Settings: your languages, display options (romanization, the native-language line, matching the audio to your target language, video quizzes), flashcard preferences, review reminders, and Site access, the list of websites where the any-website mode is on (see /any-website/).

Flashcards and the Trainer are different things: Flashcards review individual words on an FSRS schedule, while the Trainer replays whole quiz questions from the videos you watched.

Study time: what counts

The Study time card counts minutes of active learning, not minutes of video.

A minute counts when you do something that shows you are learning: hovering words for translations, opening a word explanation or a sentence breakdown, reviewing flashcards, answering quiz questions (skipped ones do not count) or taking a placement test. Gaps of up to four minutes between actions count as part of the same session, so reading an explanation or thinking about an answer is included. A single hover with nothing else around it counts as zero, and watching without interacting does not count at all.

The card shows Today, your Total and your Daily average over 7 days, 30 days or all time. Because passive watching is excluded, the number reflects the time you actually spend working on the language, which helps you check whether your habit matches your goals. For a sense of scale, the US Foreign Service Institute estimates roughly 600 to 2,200 class hours for an English speaker to reach professional working proficiency, depending on the language (see /glossary/#fsi-categories).

Phones, tablets and installing the web app

The web app works in any modern browser; watching with FlixFluent needs the extension on a computer.

Flashcards, the Trainer, tests, My Dictionary, the catalogue and Settings all work in a phone or tablet browser, with swipe gestures for grading flashcards. On a phone, catalogue titles open in Netflix or YouTube without FlixFluent, because browser extensions cannot run inside the mobile apps.

You can install the web app to your home screen, where it appears as "FlixFluent Web", and turn on browser notifications to be reminded when flashcard reviews are ready. A native iPhone and Android app is in testing and not yet available in the app stores.

For teachers: school accounts

Language schools can get a school code and a Students page.

Students who join FlixFluent with a school's code appear on the teacher's Students page with their email address and when they were last active, plus a daily activity view, study time, new words looked up, explanations and sentence breakdowns opened, flashcard reviews and quiz results, over 7 days, 30 days or all time. School accounts are set up by the FlixFluent team: email mail@flixfluent.com.

The web app and the extension share the same 24 interface languages.

Interface languages: English, Korean, Japanese, Spanish, French, German, Vietnamese, Arabic, Hindi, Indonesian, Italian, Polish, Portuguese, Russian, Thai, Turkish, Uzbek, Swedish, Norwegian, Dutch, Greek, Ukrainian, Slovak and Danish. You sign in with Google, Microsoft, Kakao or Naver, and the same account works in the extension and the web app.
