About this app

Flash Fluency is an all-in-one Korean app, from Hangul to fluency.
So is every other app. Here's what's different.

CONTENT-TO-CURRICULUM
Song lyrics, a news article, your class notes, a drama script. Bring any
Korean you actually care about and Flash Fluency pulls out every vocab word
and grammar point, then teaches them to you in new sentences.

SYLLABLE-LEVEL PRONUNCIATION FEEDBACK
AI feedback on every syllable you speak, covering every Korean pronunciation
rule. Your recording beside a native voice, block by block, so you know
exactly what you got wrong and how to fix it.

TRANSLATION COACHING
Write real Korean from your first lesson. Every sentence comes back with
corrections, naturalness tips, and style notes, down to the particle.

+1 AND SRS
Each sentence introduces exactly one new concept, so you're never lost.
Spaced repetition brings it back right before you'd forget it.

SKILLS THAT STACK
Read it, hear it, recall it, translate it, speak it. Each stage feeds
the next.

Complete beginner? Start with the Hangul course, then Korean Fundamentals.
No prior Korean needed.

Coming soon: conversational exercises, AI-assisted writing, and a
10,000-word TOPIK learning order.
