Whatsapp made my daily working easy, an amazing application with superb audio, video, and text messaging. It's an easy to use free platform which just needs internet connectivity. It has a lot of unique features, like Photo sharing, File transfer, video calling, and much more. Whatsapp is also playing an important role in business activities, a lot of business groups on Whatsapp are doing their business activities successfully through this platform. I have also used Whatsapp for reviews sharing, and getting updates from my colleagues about their jobs through Whatsapp. It works only through internet connectivity, which is a major drawback of Whatsapp. It also needs stable connectivity for video calls.
