The Bottom Line
- <strong>Anki</strong>: most powerful algorithm (FSRS), most customisable, steepest learning curve, largest medical deck ecosystem.
- <strong>RemNote</strong>: combines note-taking with spaced repetition — good if you want one tool for both. Less medical community support.
- <strong>Quizlet</strong>: easiest to start, best for collaborative decks, weakest spaced repetition algorithm, limited for long-term exam prep.
The flashcard app you choose matters less than how you use it — but it does matter. A tool with a strong scheduling algorithm (spaced repetition) will produce better retention than one without. A tool you actually use daily beats a 'perfect' tool you abandon after two weeks. This guide helps you pick the right tool for your situation, then use it effectively.
1
Anki — the power tool
Strengths: FSRS (Free Spaced Repetition Scheduler) is the most evidence-aligned scheduling algorithm available. Massive ecosystem of pre-made medical decks (AnKing, Zanki, Pepper). Fully customisable card types (cloze deletions, image occlusion, multi-field). Syncs across devices. Free on desktop and Android. Weaknesses: steep learning curve, ugly default interface, iOS app is paid, overwhelming number of settings. Best for: serious exam prep over months/years where you want maximum retention efficiency.
2
RemNote — the integrated tool
Strengths: combines note-taking and spaced repetition in one app. You create notes and automatically generate flashcards from them. Clean interface. Good for people who want a single tool for learning. Built-in spaced repetition algorithm. Weaknesses: smaller medical community (fewer pre-made decks), less customisation than Anki, algorithm is less mature than FSRS. Best for: students who want an integrated note-taking + review system and are willing to create their own cards.

Quizlet — the easy start
Strengths: lowest barrier to entry, excellent for collaborative decks (study groups), clean mobile experience, gamification features. Weaknesses: the 'Learn' mode uses a simpler algorithm than true spaced repetition, limited long-term scheduling, paid features gatekept. Best for: short-term revision, collaborative study groups, and people who need the simplest possible tool to start a flashcard habit.

How to choose
If you are preparing for a high-stakes exam (USMLE, MRCGP, PLAB, AMC) over 3+ months: Anki. The algorithm advantage compounds over time. If you are a medical student who wants one tool for notes + review: RemNote. If you need something quick for a study group or short-term revision: Quizlet. If you have tried Anki and abandoned it twice: RemNote or Quizlet with consistent use beats Anki gathering dust.

The tool matters less than these habits
Regardless of which app you choose: (1) Reviews first, always — clear your due pile before adding new cards. (2) Cap new cards aggressively — 5–15/day to prevent review debt. (3) Make cards that test decisions, not paragraphs — 'First-line for X?' not 'Describe the management of X'. (4) Delete or suspend cards that are too easy or too vague. A lean deck beats a bloated one.
The pre-made deck trap
Pre-made decks (AnKing, Zanki) are valuable starting points, but they can create a false sense of progress. If you are reviewing cards you do not understand, you are memorising patterns, not learning medicine. Suspend cards that are beyond your current level and unsuspend them as you study those topics. A curated subset you understand beats a full deck you blindly review.
