. There are so many reasons why I like whatsapp and not any other applications reasons are mentioned below.
first thing first whatsapp is I think the simple and easy messenger and anyone from any age group can use this. I think that is the main reason why its so popular and successful than any other available in market right now. the concept is very good and easy to user.
second thing is the design and layout according to me the new updates of whatsapp is not too good is what I felt beacuse the older one was much easier and user friendly. so I think whatspp should make the changes but it should be more user friendly.
whatspp gives lots of functions to user. and as I mentioned earlier so they are also very easy to use I mean you can simple send videos/images/ and there are new features which have been added like now you can also send pdf file and you can also watch video without downloading. which is very userfull.
