About this app
You know that feeling? You've learned everything, and a week later, half of it's gone. That's exactly where leef comes in. Gamified learning that actually sticks.
With streaks, a learning tree, achievements, and your own in-app currency, "Leefs," learning suddenly feels like a game you want to win, instead of a chore you're putting off.
This is how you stay on track!
Your streak brings you back every day. If you lose it, you'll feel it a little. If you maintain it, a good intention effortlessly becomes a habit. Your knowledge tree visibly grows with every study session, achievements celebrate your consistency, and you unlock themes and tree styles with the Leefs you earn. And when exam season or final exams approach, you don't have to go through it alone: in friend challenges and real-time learning spaces, you learn together with others.
And the method behind it? It's actually researched!
Simply upload your PDF, script, photo, or document. Leef reads the content and creates effective flashcards in seconds. The rest is handled by the FSRS-v6 algorithm, the same spaced repetition method that learning research has relied on for decades: It shows you each card precisely when you would otherwise forget it. No more mindlessly clicking through 200 cards, just what matters right now.
This way, vocabulary, advanced high school material, and exam knowledge stick—not through cramming late into the night, but through perfect timing. Whether you're in high school or university, Leef adapts to your pace.
A quick note for parents reading along:
Leef costs €4.99 per month, less than a single tutoring session. Your child learns every day, based on a scientifically validated method instead of guesswork. All data is stored on EU servers in Helsinki, completely ad-free and tracking-free, fully GDPR compliant, and the account can be deleted at any time.

What’s new
Der Start geht jetzt durch. Statt einer leeren Fläche siehst du das Blatt, bis
wirklich alles bereit ist, und bei vollen Konten dauert das Vorbereiten des
Baums Sekunden statt einer Minute.
Der Baum sieht aus wie gemeint: scharfe Blätter mit sichtbarer Aderung, spürbar
mehr Wind in der Krone, kein Stocken beim Wechsel.
Neu: Du kannst Konten blockieren. Wer dich stört, verschwindet aus dem
Marktplatz.
