About this app

Flash Fluency is an all-in-one Korean app from Hangul to fluency. So is every other app - here's why we're different.

Pronounce it right. Syllable-level AI feedback covering every Korean pronunciation rule. Know exactly what you're getting wrong and how to fix it.

Build sentences early. Our AI sentence coach has you writing real Korean and gives you feedback on how to improve.

Always the right lesson, always the right review. The +1 system teaches one new concept at a time so you're never lost. Spaced repetition brings it back at the right time so you never forget.

Frictionless learning. Tap any vocab or grammar point in any lesson for an instant explanation along with detailed lessons.

Coming 2026: Conversational exercises, AI-assisted writing, and a content-to-curriculum system — upload any material and learn from it.
