KakaoTalk is available for the iPhone, for Android phones, for BlackBerry and Windows Phone, and works on Wi-Fi and 3G networks.

KakoTalk has around 150 million users, which positions it among the most used instant messaging apps around. However, it is far behind WhatsApp, which features more than a billion users, and a bunch of other very popular apps.

The app integrates your contact list and adds friends automatically to your chat sessions once they are online.

You can also register your favorite friends. The app provides funny voice filters that you can apply to your voice when engaged in voice calls. It also gives useless but funny emoticons, that are animated.
