Deck Lens

Study smarter, not harder.
Deck Lens is a clean, focused flashcard app built for learners who love Anki but want a more modern experience on their phone. Import your existing Anki decks, study with proven spaced repetition, and watch your progress grow — all without the clutter.
Import Your Anki Decks Instantly
Already have .apkg files? Just open them in Deck Lens. Your cards, media, and deck structure come along for the ride. Switching from Anki has never been easier.
Spaced Repetition That Works
Deck Lens uses the SM-2 algorithm — the same proven system behind Anki — to schedule your reviews at the perfect time. Rate each card as Again, Hard, Good, or Easy, and the app handles the rest. You'll see exactly when each card comes back before you tap.
A Study Experience You'll Actually Enjoy
Flip through cards with smooth animations, track your session progress, and get a summary when you're done. Set daily review limits so you never feel overwhelmed.
Swipe Mode
Prefer gestures? Swipe through your cards for a fast, tactile study flow.
Know Where You Stand
Check your stats anytime: review heatmap, retention rate, streak counter, and cards broken down by status (new, learning, review). See what's working and where to focus.
Create and Edit Your Own Decks
Build flashcards from scratch or tweak imported ones. Deck Lens supports rich card content so your notes look the way you want.
Export and Share
Export any deck back to .apkg format and share it with friends, classmates, or your other devices. Your data is always yours.
Available in English, German, and Turkish.
Whether you're learning a new language, studying for exams, or memorizing anything else — Deck Lens gives you the tools to make it stick.
