@grits English is my first language as well. I personally recommend learning the consonants Hangul, then the vowels. This will serve your purpose greater than any of the apps. Already know English gives you a huge advantage at learning Hangul. Once you learn the consonants, I've notice it transfers over to Chinese and Japanese pretty easily.
@HSK4096 thank you for the advice!! to be honest i have much more trouble with listening than reading, and it's indeed those dang consonants!! they sound so similar to me 😭
