Whatsapp is one of the best social networking application I have ever used. best part of this messenger is that I can only chat to my known friends. the person who are in my contacts list and using the whatsapp I can chat to them. it has severall features like I can send pictures , videos, audio files, chat in group, whatsapp call , send crazy emoticons.
The best part is I can see the last seen of my friends although there is a feature we can hide our last seen as well but still is the best for day to day chatting. blue tick mark feature is also quite unique as I can see that my msg has been send and read by my friend. its free to download on any operating system and no subscription is required its lifetime free. soon whatsapp is also bringing the video call feature as well.
