Whatsapp is a good concept to connect with peoples. We can chat to our friends personally or in groups also.
Design is so simple and easy to understand for users. It consume much less data and even connected in low speed data.
Features are like chat , voice call and video call are awesome. We can share contact numbers photos and videos. Voice and video quality are good. I can change the wallpaper of any chatroom which is one of my favourite function.
It is very useful app for me because my all friends and relatives are on whatsapp. We made a group name ’all together ’ and we chat all the time. We share photos too much. Whatsapp make work easy and fast in any kind of business or work. Very useful.
