It’s been 6 years I am using whatsapp.The whatsapp is the best online messaging app. The best because currently whatsapp had more features than messaging like Voice calling, Video calling, Conference calling etc.The best thing about whatsapp is that it can be used as a messaging app and as well as a social media app.In the earlier stages I used to only text on whatsapp and ot kept on growing exponentially. Then they added many features little by little such as statuses sharing, Arranging Multiple photos automatically in a single folder, Group chatting etc. Including various calling features.And now whatsapp is the most used messenger worldwide.Another best thing about whatsapp is we can do international calls for free. Like we can freely do video call and voice call to the people in the other countries like US, Canada, Dubai, Germany etc.The more I say the less it is to praise whatsapp. Whatsapp is more than a messaging app now and currently whatsapp has become a contact hub for all the businesses as well.Because of whatsapp’s excellent management technology and design also because of its unique features and usefullness whatsapp remains the best.
