12levels: English Vocabulary app analytics for September 2

12levels helps you build real English vocabulary — and actually keep it — with the science of memory. Most apps make you cram. 12levels uses scientific spaced repetition (the open FSRS algorithm) to show you each word right before you'd forget it, so it moves into long-term memory with the least effort. • Learn at your exact level — a precise CEFR ladder from A1.1 to C1.3, not a vague "beginner / intermediate." • Read AI books and articles matched to your level. Tap any word for its meaning, an example, and American pronunciation. • A real-time progress map of the words you already know. • Keep your streak with goals and achievements. • Your words on the Home Screen with a large widget. Start with a 14-day free trial. Built on memory science. No ads. Subscriptions auto-renew unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings. Terms of Use (EULA): https://12levels.app/legal/terms Privacy Policy: https://12levels.app/legal/privacy
