Master the vocabulary and real phrases you'll actually use — in conversations, on your trip, and on exam day.
Flashcards are how you get there: start with ready-made decks for travel, small talk, and more, or turn your own notes, photos, and PDFs into decks with AI. Then spaced repetition makes every card stick long-term.
Study your way: flip through your cards, test what you studied with quizzes, practice & score your pronunciation, or review hands-free with Listen Mode on your commute. Track your streak, hit your daily goal, and pick up right where you left off on iOS or web.

I have to study multiple languages for my major and honestly I enjoy this app much more than Quizlet or other flashcard apps. It’s intuitive and easy and most of the app remains completely accessible which I appreciate which makes me keen to purchase the subscription for the other features. The only thing I wish there was more of is the downloadable flashcard content for different scenarios but I’m sure more will come over time. Overall 5 out of 5 for me :)

Thanks so much, Jonah! We’re really glad Kioki is helping with your language studies. Which languages are you studying, and what topics or situations would be most useful? Our team would be happy to work on decks for you!
Unable to reverse the card direction
npcarrillo09
Unable to figure out how to reverse the card deck to study. I want the front in English and flip to the language I’m learning. I’ve tried googling without figuring out a way to fix this. I’ve used a lot of different studying apps and this is the first that makes it so difficult to flip it.
Developer Response
Thanks so much for the feedback, and I'm sorry this was frustrating. I completely agree it should be much easier to study cards in either direction.The good news is we're shipping an update next week that will make this much more intuitive. Thanks for helping us improve Kioki! We'd love to hear from you once that feature is available.
