Fern is a beautiful flashcard app for learning languages. Words come from where you actually meet them: the book you are reading, a video with subtitles, a photo of a page. Everything runs on your device, with no account, no cloud and no ads. SMART REVIEW An FSRS scheduler brings a word back exactly when memory starts letting go of it. The "At risk of forgetting" section gathers what is about to slip, and "Best time to study" points to the hour when your sessions work best. The algorithm tunes itself from your own review history. 12 STUDY MODES Learn, Flashcards, Test, Match, Write, Dictation, Build a phrase, Audio, Context, Hard words, Speed review, Cram. The Learn mode walks each word up the ladder of mastery on its own, from recognition to free recall. FROM BOOKS An EPUB, FB2, TXT and SRT reader with tap-to-translate. Chapters, bookmarks, reading themes, read-aloud, paged and scrolling layouts, bilingual view with a paragraph translation. Smart analysis shows how much of a text you already know and which words to learn first. FROM VIDEO Paste a link to a video with subtitles and the lines turn into cards with translation and real-voice audio, while the video itself reads in karaoke mode. FROM PHOTOS Snap a page and Fern recognises the text, then offers the unfamiliar words as cards. Recognition works offline for Latin script. QUICK CAPTURE A word from the clipboard, an article by URL, a quick "word — translation" list. A card takes a couple of taps, translation included. GRAMMAR ON THE CARD Verb conjugation and noun forms for Spanish, French, German, Italian, Portuguese and Russian, right on the back of the card. MOTIVATION Daily goals with a progress ring, a study streak with freeze shields for the day you miss, achievements and weekly stats: vocabulary composition, parts of speech, activity heatmap, review forecast. LOOK AND FEEL Deep green theme, light and dark schemes, switching by time of day. Large tiles and live animation throughout. LANGUAGES Interface in English, Russian, German, French, Spanish, Italian and Portuguese. Over 55 study languages, plus your own custom ones. Ready-made starter decks, deck import from Anki (.apkg), CSV and TSV, vocabulary export. PRIVACY Decks, words and stats stay on the device. No analytics, no cloud backup. A backup is an ordinary file you keep yourself, and restoring it can either replace everything or merge only what is new. FERN PRO Cards, every study mode, the scheduler, stats, reminders, backups and vocabulary export are free, with no limit on decks or words. Fern Pro unlocks your own material: books, videos, articles, text recognition from photos and imported decks. The first source is free, so you can try it on your own book before paying. The subscription runs monthly or yearly and is cancelled in the app with one tap; anyone who bought Fern Pro earlier keeps it for good. The Fern Pro subscription renews on its own until you cancel it in Apple ID settings. The App Store shows the price and the period on this page.

Multibit превращает таблицу умножения в игру, которую хочется пройти до конца. Мы не заставляем зубрить. Каждый новый пример сначала появляется картинкой — ряды точек выстраиваются на глазах, и ребёнок видит, почему 3 × 4 = 12. Потом Бит, наш стеклянный маскот, подсказывает приём: удвой, половина от ×10, «десять минус один». И только после этого — тренировка, пока ответ не станет мгновенным. ПУТЬ ОБУЧЕНИЯ • 9 разделов и 49 уровней — от ×1 и ×10 до «Мастера таблицы» • Умный порядок: ×2 → ×5 → ×9 → ×3 → ×4 → ×6 → ×7 и ×8. Благодаря перестановке к концу остаётся всего 3 новых примера • 9 типов заданий: картинка-массив, выбор ответа, ввод с клавиатуры, «верно или нет», пропущенный множитель, пары, счёт по порядку • Ошибки возвращаются в конце урока, пока не запомнятся • Звёзды, сундуки с кристаллами и проверка раздела на корону ТРЕНАЖЁР — 6 РЕЖИМОВ • Спринт — сколько успеешь за 60 секунд • Шарики — лопай верный ответ, пока он не улетел • Верно или нет — свайпай карточки • Пары — находи пример и ответ • Выживание — таймер всё короче, три жизни • Дуэль — вдвоём на одном телефоне, кто быстрее • Умная тренировка сама подбирает примеры, которые пора повторить ВИДНО, ЧТО УЖЕ ВЫУЧЕНО • Вся таблица 10×10 как тепловая карта: от «новый» до золотого «выучен» • Интервальные повторения учитывают не только правильность, но и скорость: золото — только если ответ приходит без счёта • Серия дней, дневная цель, достижения ПРИЯТНО В РУКАХ • Дизайн Liquid Glass для iOS 26 • Тактильный отклик на каждое нажатие, собственные звуки, частицы и конфетти • Работает без интернета и без регистрации ЧЕСТНО • Без рекламы, без покупок, без аккаунтов • Мы не собираем никаких данных — весь прогресс хранится только на устройстве
