Anki is my pick of the best flashcard apps if you will study the same material for months and you can tolerate an interface that looks unfinished. Quizlet is the better pick when the class set already exists and the exam is soon. RemNote is the one to choose when the cards should be born inside the notes, not copied into a second app the night before.
Spaced repetition is not magic. If you make 400 cards and review none of them, you bought a typing exercise. I have that deck. It is called 'Spanish, allegedly.'
The short answer
Anki for long-term decks you control. Quizlet for shared class sets and cramming. RemNote if notes and cards have to be the same document.

Best flashcard apps
Anki
Language learners, med students, and anyone building a deck they will keep for years
Visit AnkiThe desktop app is free. The scheduler is still the standard serious decks use. AnkiWeb syncs. AnkiDroid is free. AnkiMobile on iPhone is a separate paid app, which surprises people every semester.
Search a course, start learn mode, and get through this week's list. Collaboration is the advantage over Anki. You are not hand-building every card from a textbook PDF at midnight.
Write an outline, mark a cloze deletion or a question, and review it in the same app. For lecture notes that should turn into memory, the copy-paste tax of Anki is the thing RemNote removes.
How to judge the best flashcard apps
Scheduling, editing speed, and whether you can get your cards out. A locked-in deck is a hostage. Anki's export is plain. Quizlet's is good enough. RemNote's notes are the backup if you also care about the prose around the cards.
Shared content is the other axis. Quizlet wins when the set exists. Anki wins when you care that every card was written in your own words. Cards you did not write are easier to recognize and worse to remember. That is an annoying finding if you like shortcuts.
Who should skip flashcard apps
If the exam tests essays and projects, a pile of definitions will make you feel busy. Write practice answers. Cards are for facts that have a short correct response.
If you will not review on the days you are tired, no scheduler saves you. A paper stack on the desk can beat an app you mute.
How we tested Anki, Quizlet, and RemNote
Last tested September 2026. I built a 60-card deck in each app from the same source notes: definitions, a few cloze deletions, and one image card. I reviewed for ten days on an iPhone 16 and edited on a MacBook Pro. Quizlet also got a pre-made public set so I was not only grading the DIY path.
Anki was the most honest about what I was forgetting, and the slowest to author. Quizlet was the fastest start and the easiest to over-rate because the buttons feel like progress. RemNote was awkward on day one and then the only flow where fixing a note fixed the card. I missed a review day in all three. The apps did not email me into being a better person.
I did not test classroom admin, Quizlet's live games, or Anki add-ons beyond the defaults. Medical decks with tens of thousands of shared cards are their own culture. Use a deck other students already trust, then edit it, instead of building from zero in week one of anatomy.
