Full description
Learn a word today. Still know it next year. Braintain shows you each word at the exact moment you are about to forget it. That is spaced repetition, and it is the difference between vocabulary that sticks and vocabulary that slips away. WHY IT WORKS Cramming loads words into short-term memory, where they fade. Braintain schedules every card on a proven algorithm, stretching the gap a little further each time you get one right. Five minutes a day beats an hour of cramming, and the app tells you which day to come back. WHAT YOU GET - BrainPods: curated decks you can join in one tap, in English and beyond - Your own words: add any card, in any language you are learning - Hear every word: tap the speaker for real pronunciation, or switch on auto-speak and let the deck read itself to you. Free for everyone. - Guess game: active recall instead of passive re-reading - Streaks and reminders: a nudge on the day your cards are actually due - Progress that means something: mastery derived from how you really perform, not a vanity counter HOW IT WORKS 1. Join a BrainPod, or add the words you want to keep 2. Review what is due today. It usually takes under five minutes. 3. Come back when Braintain says so. That is the entire method. START WITHOUT AN ACCOUNT Open the app and begin. Sign in later, only when you want your progress saved across devices. BRAINTAIN PREMIUM Upgrade to unlock Mira, your AI coach, who reads your actual review history and tells you what to work on next. Premium also generates definitions, examples and practice words for you with AI, and removes all ads.
