I am using this app from almost a year it is been my favorite app so far for messaging I must say that this app has decreased the communication gap between us.
I choose this software because I found this app very usefull and so far easy because we dont need id on this software just we have to add our phone number.there are many apps similar to that but I choose that because everyone was using this app and this app is also very famous. And it uses very less mb usage thats the best part I love about whatsapp.
