FlashCards 1000 — vocabulary that actually sticks Build real fluency with the 1,000 most useful words at each CEFR level—from A1 through B2. Whether you’re learning Portuguese, Spanish, or English, each deck is designed around high-frequency vocabulary so you spend time on words you’ll hear and use in real life. STUDY YOUR WAY. Flip cards with a tap. Move through the deck with intuitive swipes. Rate how well you know each word so the app can focus your time where it matters—without menus getting in the way. SMARTER REVIEWS WITH FSRS. FlashCards 1000 uses FSRS (a modern spaced-repetition system) to schedule reviews. You see words again at the right moment—before you forget—so short daily sessions add up to durable memory. RICH CARDS.
