Turn videos into language practice. Lingua Player helps you watch real content with subtitles, translate what you do not understand, save new words, and review them later with flashcards. Learn with the videos you already want to watch: - Open online videos, YouTube videos, and local files - Add or select subtitles for your video - Transcribe videos in real time — subtitles appear as you watch - Translate subtitles into your native language - Save unfamiliar words while watching - Review saved words with spaced repetition flashcards - Study offline with local videos, subtitles, and offline translation - Transfer videos and folders to your iPhone over Wi-Fi Lingua Player is built for learners who want more than a standard video player. Instead of switching between a player, translator, notes app, and flashcard tool, you can keep the whole study flow in one place. WATCH WITH SUBTITLES Use subtitles to follow natural speech in movies, lessons, web videos, and your own video files. Lingua Player supports videos from the built-in browser, YouTube, the file system, and offline storage on your iPhone. TRANSLATE WHILE WATCHING Translate subtitles when a phrase is unclear. Online translation services are available, and offline translation helps you keep studying when you do not have a stable internet connection. BUILD VOCABULARY FROM REAL CONTEXT When you find a useful word, save it from the video and review it later. Flashcards are connected to your learning flow, so new vocabulary comes from the content you actually watch. REVIEW WITH SPACED REPETITION Saved words can be practiced with a simple flashcard trainer based on spaced repetition. Words that need more work appear more often, helping you build long-term memory. STUDY ANYWHERE Prepare videos in advance, use local subtitles, and keep learning on the road, during flights, or anywhere without reliable internet. Lingua Player supports 100+ languages and is designed for learners who want to make regular video watching part of their language routine.

WatchLearn помогает подготовиться к фильмам и сериалам на английском до просмотра. Вместо случайных слов вы учите лексику, фразы, идиомы и сленг из конкретного фильма или серии, которую действительно собираетесь смотреть. WatchLearn не показывает фильмы и сериалы внутри приложения. Он помогает заранее подготовить словарь, а смотреть вы будете там, где обычно смотрите. Как это работает: 1. Найдите фильм или сериал 2. Посмотрите слова и фразы, которые стоит знать заранее 3. Потренируйтесь в карточках и быстрых квизах 4. Смотрите увереннее и меньше зависите от субтитров Каждая сессия короткая и сфокусированная. Повторяйте полезную лексику, проверяйте себя за несколько минут и привыкайте к живым диалогам, а не учебным примерам. Возможности: - Слова и фразы из фильмов и сериалов на основе субтитров - Живая разговорная лексика, идиомы и сленг - Карточки со свайп-обучением - Квизы с вариантами ответов - Личный словарь по выбранным фильмам и сериям - Отслеживание прогресса - Темная и светлая темы - Интерфейс на английском, русском, украинском, испанском и французском Полный доступ открывает подписка. Первые 3 дня — бесплатно, дальше подписка продлевается автоматически; отменить можно в любой момент в настройках Apple ID. Бесплатного тарифа без подписки нет. Подготовьтесь заранее. Смотрите с большим пониманием. Условия использования (EULA): https://watchlearn.online/terms-of-service.html Политика конфиденциальности: https://watchlearn.online/privacy-policy.html
