I have been using the whatsapp for 4 years from 2015. This is the best app for chatting as well as we can also make voicecall videocall and can add up our daily status.
Layout and design-The primary concept is old and able to chat.That has been enhanced to communication by various means with good GUI.There is space for text windows in screen.
The icon is a green bubble sign.
Feautres-
Installation-This app is easily installed with less data pack. This can be find in play store and When you ever installed your contacts saved join automatically with you on whatsapp. So it is a brilliant way of communication and you can join some study groups also.
