K Flash: Korean Flashcards

K Flash is a Korean language study app for serious learners. Spaced repetition that adapts to your pace, opinionated card design, and no shortcuts.

Six decks:

• Vocabulary — thousands of cards verified against the National Institute of Korean Language, with glosses, parts of speech, frequency rankings, and corresponding hanja
• Phrasebook — everyday Korean phrases with politeness-level callouts
• Hangul — from individual jamo to the rules of syllable blocks
• Grammar — verb endings, particles, sentence patterns, and usage context
• Hanja — the 한국어문회 배정한자 levels with readings, meanings, and compound examples
• I Ching — the sixty-four hexagrams in James Legge's public-domain translations

Four practice modes:

• Browse — read at your own pace, flip cards, mark favorites
• Study — spaced repetition tracking your mastery card by card
• Quiz — diagnostic tests with bronze, silver, and gold tiers
• Quick Study — short cross-deck sessions for daily check-ins and supplmentation

Built thoughtfully:

• No ads, no analytics, no tracking — your data is yours alone
• Optional iCloud Sync and Backups — automatic snapshots to your private iCloud, restorable anytime, never visible to anyone but you
• Apple's Premium and Enhanced Korean Voices available for press-and-hold audio examples
• Study reminders and streak-saver notifications
• Light, dark, and monochrome modes
• Export and import anytime; one-tap erase
