InfinityEnglish

Learn English with structured CEFR-level courses, smart vocabulary practice, homework, and live one-on-one classes with your teacher — all in one app.

InfinityEnglish is a focused way to learn English — from your first words to confident, advanced fluency. Every part of the app is designed to do one thing well: get you reading, listening, recalling, and using English a little better every day.

WHAT'S INSIDE

• Structured courses for every CEFR level Six carefully sequenced levels — Elementary, Pre-Intermediate, Intermediate, Upper-Intermediate, Advanced, and Proficient — so you always know what to study next and never get stuck on material that's too easy or too hard.

• Lessons that respect your time Each lesson is broken into short, readable sections you can finish in one sitting. Read-status syncs across devices, so you can pick up exactly where you left off.

• Vocabulary that actually sticks Add any word you meet to your personal vocabulary. The app uses spaced repetition to bring words back at exactly the moment you're about to forget them. Practice in classic flashcard mode or quick 4-option quizzes.

• Translations in your language Definitions and example sentences are shown with translations in English, Russian, or Ukrainian. You can also override the translation for any word with your own note.

• Homework that's more than multiple choice Cloze (fill-in-the-blank) tasks, multiple-choice questions, and free-response answers, all graded automatically where possible. See exactly which answers were right and where to focus next.

• Live one-on-one classes Your teacher schedules sessions for you and shares the meeting link right in the app — no email digging. You get a reminder before each class and a clear "your class link is ready" notification when it's time to join.

• Audio everywhere Tap any word or sentence to hear it pronounced clearly.

• Light & dark themes A clean reading experience day or night.

• Three interface languages English, Russian, Ukrainian.
