QuackDeck is an Android flashcard app that writes cards for you and schedules them with FSRS. Paste notes, type a prompt or add a document, and AI turns it into question-and-answer cards; AI Deck Review flags duplicates, confusing wording and likely mistakes. Anki users can import .apkg and .colpkg decks, images and audio included. Cards can be text, image, audio, cloze or mix-and-match, with LaTeX and mhchem for maths and chemistry, and it can read the text from a photo of printed notes. It works fully offline with no account. The free tier is ad-supported and is not a trial; Pro adds cloud sync, a monthly pool of AI tokens, study groups and no ads.

QuackDeck is made by Fun Stuff Studio, a small independent studio. It began with a simple observation: spaced repetition is one of the best-proven study methods there is, yet most students give up on the tools that offer it because they feel like spreadsheets. The goal was to keep the science (FSRS scheduling, full Anki compatibility) and wrap it in something warm and encouraging. That meant a duck who celebrates your streaks, colours that match your mood, and AI that handles the tedious part of writing cards. That way students spend their time remembering instead of formatting.
QuackDeck pairs a serious memory engine with an app that's fun to open. Under the hood it runs FSRS, the same modern spaced-repetition algorithm power users set up in Anki, plus full .apkg import. On top of that, AI writes your cards from your notes and checks your existing decks for duplicates and mistakes. Quacky, a duck mascot with five moods, cheers you through streaks and milestones. Most apps are either powerful but clinical, or friendly but shallow. QuackDeck aims to be both powerful and friendly.
It's less work to start. Paste your lecture notes and you have a deck in seconds, or bring your existing Anki decks with their media. It schedules smarter. FSRS is the default on every deck, so there's nothing to configure. It's honest AI. You approve every generated card, and Deck Review marks possible factual issues as "verify yourself" instead of stating them as fact. It's social for free. Study Groups, leaderboards and tournaments cost nothing. It works offline, and your decks live on your device.
High-school and university students preparing for exams. That includes finals, A-Levels, and medical and entrance exams such as the MCAT, USMLE and NEET, plus language learners building vocabulary. They study in short daily bursts between classes. They want the results of spaced repetition without the learning curve of traditional flashcard tools. The app is for ages 13 and up.
