Membra: Vocabulary Builder

Add the word you just met. Remember it a week later. Then duel a friend over it. Membra does not hand you someone else's word list. You add the word you heard in a show, read in a paper, or wrote down in class — and Membra brings it back on the day you were about to forget it. NO LIMITS ON LEARNING No energy. No hearts. No daily lesson cap. Add as many words as you like, review as long as you like, duel as often as you like. YOUR OWN DICTIONARY Type into two boxes. Membra works out which language you typed in, translates it, and files it on the correct side. Every language pair gets its own dictionary — your English one and your German one stay separate — and you move between them with a single gesture, the way you switch apps on your phone. SPACED REPETITION THAT ACTUALLY MEASURES YOU Membra never asks you to rate yourself. It watches how you answered: how long you took, whether you used a hint, how many wrong keys you pressed. The schedule is built from that, not from a button you pressed out of habit. Four review modes: flashcard, multiple choice, typing, and mixed. When nothing is due, free practice opens — and a correct answer in free practice will never distort your schedule. REAL-TIME WORD DUELS The thing nobody else in this category has: live 1v1 word duels. The attacker picks which word to send — but choose something too easy and a fast answer comes straight back at you. It runs until one tower falls. No opponent around? Eleven training opponents are waiting, each with its own accuracy, its own reaction speed, and its own trash talk. When the match ends, you can pull any word from it straight into your dictionary. READY-MADE PACKS Academic IELTS vocabulary, level-by-level English (A1-C2), plus topic packs: business, technology, health, environment, everyday essentials. All free, added in one tap. HABIT Daily streaks with a freeze to protect them, daily and weekly quests, ranks, monthly leagues and a leaderboard. Add friends, nudge them, send them a word, see who is ahead. LANGUAGES Interface: English, Turkish, German, French, Spanish. Dictionary languages: English, Turkish, German, French, Spanish. AN HONEST NOTE Membra is not a language course. If you are looking for a curriculum that starts at A1, this is not it. If you want to collect the words you actually meet and make them stick, you are in the right place. We do not sell your data. We do not run ad networks. You can delete your account completely, at any time.
