It is a messaging app which is used in multiple platforms. This application is used by people for making video and audio calls and also to chat with other persons. I use the whatsapp application for my study purposes (i.e. to save my notes) and also to chat with some friends.

Yes whatsapp made the life of many peoples very easy. Because when Covid-19 was come we also take our university lectures with the help of whatsapp. We can also do vidios and audio calls with the help of whatsapp. Thanks for sharing with us. Best of luck..
