Deck Lens vs Pith

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.

Pith helps you remember what you study, and stays out of the way while you do it. Make a card, or bring in the decks you already have, and let spaced repetition resurface each one at the moment you are about to forget it. No streaks to keep alive, no clutter. Just the next card, at the right time. It is built to feel like a small-press notebook rather than another grey app screen: serif type, warm paper tones, and a study flow with nothing in your way. REMEMBERS FOR YOU Every card is scheduled with FSRS, the modern spaced-repetition algorithm, so reviews land right before recall would slip. Prefer the classic method? Switch to SM-2 in a tap, and imported decks keep their own schedule. BRING YOUR DECKS Already use Anki? Import your .apkg files with cards, media, and progress intact, then export back out the same way. Spreadsheets come in too, through CSV or TSV. MORE THAN WORDS Add images, record or attach audio for pronunciation, and choose the card type that fits the material: basic, reversed, type-the-answer, cloze deletions, or image occlusion for diagrams and maps. BUILT FOR BIG DECKS Thousands of cards stay fast. Browse, search inside a deck, and study large imported sets without the app slowing down. SEE YOUR PROGRESS Retention rate, review history, a study heat map, and an upcoming-reviews forecast, each broken down per deck. ON EVERY APPLE DEVICE A native app for iPhone, iPad, and Mac, with a Today widget that keeps your reviews one glance away. PRIVATE BY DESIGN No account. No ads. No analytics or trackers of any kind. Your cards stay on your device, and with Pith Pro they sync through your own iCloud, which we never see. FREE, WITH ONE OPTIONAL UNLOCK Free includes one deck with unlimited cards and the full study experience. Pith Pro is a single $5.99 purchase, never a subscription. It unlocks unlimited decks, iCloud sync across your devices, and the cloze and image-occlusion card types. Questions or ideas? Email claudiu.sararu@gmail.com.
