The best messaging app that is whatsapp.
The whatsapp is now worldwide that all people use it. This app has develop vert fast and it has 100 m users. Now we can experience vedio call and hd voice call in fast network speed. If u see whatsapp have many trick and tips that u can watch in youtube and bow new feature is that u can read others message also by using barcode scanner is the best. Whatsapp can connect u to world with no cost and it will take some data. The design and layout of whatsapp is best.
I Think it will be more develop in feature as best connectivity app.
