Yoki — это самый простой способ выработать привычку учить английский и турецкий. Мы начинаем с этих языков, но список будет пополняться. Никакого шума, геймификации и сложного интерфейса. Только вы и слово, которое нужно запомнить. ПОЧЕМУ YOKI? Мы ценим ваше внимание и время: — Мгновенный старт: не нужно регистрироваться, чтобы начать учить слова прямо сейчас. — Чистый интерфейс: без запутанных меню и лишних кнопок. Вы просто запускаете приложение — и сразу начинаете учить. КАК ЭТО РАБОТАЕТ? В основе Yoki лежит метод интервального повторения (Spaced Repetition). Умный алгоритм сам знает, когда показать вам карточку, чтобы слово перешло из кратковременной памяти в долговременную. НАШ СОВЕТ Сделайте обучение ритуалом. Заходите в Yoki дважды в день — за утренним кофе и перед сном. Всего 5 минут в день помогут встроить сотни новых слов в вашу речь. Скачивайте Yoki и пополняйте словарный запас без стресса.

Sonic turns the words you want to learn into flashcards and helps you remember them for good. MAKE A SET IN SECONDS • Import by link: paste a link to a public card set and Sonic brings in every term and definition. • Paste text: a list of words with their translations becomes cards, one pair per line, split by a dash, colon, comma or tab. • Check everything in the preview, fix or remove cards, then save. • Or type words yourself, one card at a time. FIVE WAYS TO STUDY • Flashcards: flip each card and mark it Know or Still learning. The next round brings back only the cards you are still learning. • Practice: short rounds that start with multiple choice or true or false and move on to written answers as you improve. • Test: choose how many questions and which kinds, and check yourself before an exam. • Match: pair each term with its definition to clear the board, and race your best time. • Review: spaced repetition brings each card back just before you would forget it. LEARN EVERY DAY The Learn tab gathers the cards due today from all your sets, plus the number of new cards per day you choose. Answer them, and Sonic schedules the next review for you. HEAR EVERY WORD Tap a word to hear it spoken. Sonic recognizes the language of each side and reads it aloud with the voices on your iPhone, in many languages. YOUR DATA STAYS YOURS • No account and no sign-up. • No ads, no tracking, no analytics. • Your sets, progress and settings sync through your own iCloud to your other devices. • Share any set as plain text.
