KakaoTalk

KakaoTalk is the Windows version of this well-known IM and free calls app. With this program, users can talk for hours with as many friends as they like, whether it's one-to-one or in groups of up to five people.

Using this tool is as easy as pressing run. To start any conversation, you just have to click on a friend and press the call key. It is worth highlighting that you can interact with KakaoTalk users via calls or chats, using different emojis or even changing your voice to sound like a dog or cat. With this app, fun is guaranteed.

The calls are of good quality, without abrupt cut-offs or lags that usually occur in other tools of this genre. What's more, you can adjust the volume to your preference. Additionally, the KakaoTalk chat windows can be customized with different colors, themes and totally unique designs created from your own photos.
