Last updated: 16 October 2026
Korean Cards is an offline flashcard app for learning Korean on iPhone and iPad. It is coming soon to the App Store. This page is the official support channel.
Frequently asked questions
Is it a subscription?
No. Korean Cards is a one-time purchase. There are no subscriptions, no in-app purchases and no ads.
Does it need an account or an internet connection?
No to both. The words, sentences, lessons, readings and practice tests are inside the app, and the app makes no network requests in normal use.
Which levels does it have?
Six levels, from Beginner 1 to Advanced 2. They are built from the learner dictionary of the National Institute of the Korean Language (NIKL) and from word frequency. They are not TOPIK levels, and the app does not tag words with TOPIK levels.
Are the practice tests real TOPIK papers?
No. The app has 20 original practice tests written in the TOPIK format: 10 in the style of TOPIK I and 10 in the style of TOPIK II. They copy the format only. They are not real exam papers, and Korean Cards is not affiliated with NIIED, the organisation that runs the TOPIK.
What does the AI tag mean?
A small "AI" tag marks content that was written with a language model. This covers example sentences that do not come from Tatoeba, memory aids, usage notes, idiom write-ups and notes on similar words. The models were DeepSeek-V4.1-Flash, Kimi K3 and Claude Sonnet 5.5, working from the NIKL data, and the results were reviewed. They can still contain mistakes. The grammar lessons, drills, readings, practice tests and exercises on similar words were also written with Kimi K3 and Claude Sonnet 5.5 and reviewed before release. The data page lists the sources.
How do I move my words to or from HangulHover?
HangulHover is the companion app for the Mac, also coming soon. The exchange uses files. Nothing goes through a server. To bring words into Korean Cards, open Settings and choose Import vocabulary, then pick a HangulHover file (.koreancards), which also carries your review history, or a HangulHover CSV export. Your existing progress is kept. In the other direction, Export progress in Settings creates a backup file that you can send to your Mac with AirDrop or any other way you like.
How do I back up my progress?
Open Settings and use the Backup section. Export progress saves a file with your cards, review history, personal deck and settings. Restore from backup reads such a file and merges it into the app. Restoring never deletes anything. Use this to move to a new device or to keep a copy of your progress.
Can I use the dictionary data?
Yes. The combined Korean data is distributed under CC BY-SA 4.0. The data page lists the sources and licenses and explains where the data is.
What data does the app collect about me?
None. See the privacy policy for details.
