Missing english word in korean – Korean - English Dictionary & Phrasebook / 영한사전 Review

For example, “invariant”, “peritectic” and “isomorphous”. I was looking to find the meaning in korean and it didnt come out so i had to use other dictionary to find it. Well, I'm deleting this app but im leaving my comment here so developer will know what is missing.
