Hangul Practice Взлом 1.0 + Чит Коды

A simple app designed to help you practice reading Korean.

With it you can get familiar recognizing the characters (Jamo).
If you forget how something is pronounced, try playing the word. Siri will read it to you and give you a hint of how it's supposed to sound.

Disclaimer:
Siri might not be the best source of knowledge when it comes to pronunciation. Take it more as a way to make sure you recognize each Jamo.
It's still recommended you ask someone who speaks the language in matters of pronunciation.
