KakaoTalk

Kakao Talk is the Mac version of the popular instant messaging and free voice-calling application. With this program, users can talk for hours with all their friends, whether it be one-on-one or in groups of up to five people.

Using this tool is very simple. You just click on a friend and press the call button. You can interact with other Kakao Talk users either by calling or chatting with them. The chat allows you to use emoticons and the calling option allows you to change your voice so that it sounds like a cat or a dog, which is guaranteed to give you some fun.

The calls have great quality and will not cut off or delay your voice, which is something that frequently occurs when you use other applications of this sort. Additionally, you can adjust the volume to the level that's best for you. And, the chat windows of Kakao Talk can be customized with various colors, themes, and totally unique designs where you can use your own photographs.
