About this app

LetsLearn teaches vocabulary the way memory actually works: tap a card, flip it, say whether you knew it, and let spaced repetition bring the hard words back right before you would forget them.

🃏 3,000 words, six CEFR levels
Every word belongs to a level from A1 to C2 - 500 words each - so a beginner sees numbers, colours and family while an advanced learner works on idioms and specialist terms. Pick your level once; the categories filter inside it.

🌍 Four languages, twelve directions
Turkish, Dutch, English and German. Choose your native language and the one you are learning; any pair works in either direction, and your progress is kept separately for each pair.

🔊 Hear every word
Each card carries clear pronunciation audio, a slow version, the phonetic transcription and an example sentence with its translation. German and Dutch nouns come with their article.

🔁 Spaced repetition that respects your time
"I know it" pushes a word out to 1, 3, 7 and 16 days, then further. "Again" brings it back in ten minutes. Words move from New to Learning to Learned to Well learned - nothing is repeated more often than it needs to be.

📚 Browse the whole vocabulary
Nine everyday categories - home, groceries, school, work, food, travel, health and more. Search all 3,000 words, keep favourites, and see the list of everything you have learned.

🎯 Daily goal and streak
Set a daily goal, watch the ring fill up, and keep the streak going. The week view shows which days you studied.

📱 Interface in English, Turkish, German and Dutch. Start right away as a guest - an account is optional and lets you keep your progress across devices.

Free and paid
The first 50 cards are free. Unlimited study needs LetsLearn Premium, a monthly or yearly subscription that also removes ads. The free version shows a small banner ad; a one-time purchase removes ads without a subscription. Subscriptions renew automatically and can be cancelled any time in your Google Play account.
