Whatsapp is a social app.
Some features of whatsapp -
1.It can be used for chating individually with friends or family or in group.
2.It can be used for calling.
3.It can also be used for video calling.
Now, Its time for cons -
1.Whatsapp popularity is decreasing day by day.
For ex- Before I was using whatsapp for 2-3 hours.But now Im using it only 10-20min per day.
2.It has very less stickers for showing emotions or feelings.
3.Its video calling feature is very poor.
4.Its interface is very complex.
5.If you are in a group then if anybody sends a message everybody then you get 2 message( One from your friend or family member another from group) .Now think if he send 20 messages then you will get 40 messages and so on.
6.It has many bugs.
7.It is unstable when you are receiving about 50 messages per second.It means it has not a capacity to defend itself.
Thank You!
