This is an app. called Kakao Talk which you can chat and call with your friends. To compare, it is similar to WhatsApp, but I find Kakao Talk cooler because it has various of emoticons and you can do many other things. As you watch the first video, you can see some of the emoticons that this app. offers. I know that some of EAS students already has this app. (I don't refer to only Koreans). Even seniors all have Katok (Kakao Talk) in their phone and always talk in a group chat. I'm not sure about spanish, but you can (if you want) download this app. in English version. I really recommend this app, because you can also enjoy many games like "Cookie Run", "Wind Runner", etc. with your Katok account. Also, for people that maybe needs some instructions on how to use this app, second video will tell you basic things.
Well, you might not like it. However, try it! You will love to use those funny and cute emoticons.
Thank you for your time to read my blog post. Honestly, I didn't know what to write.
