Life is becoming difficult without WhatsApp. This hugely popular app now has more than two billions active users. It lets users text, call, and video chat with others anywhere for free, thus helping people save money. It is the easiest way for people to share photos, audio messages, contacts and video. It is also pervasive, available on iOS, Android, Windows Phone, and BlackBerry devices.

WhatsApp has changed the way we communicate by making it easier and more convenient to stay in touch. Whether you're catching up on the latest news or planning a vacation, the app is perfect for staying connected to family, friends and colleagues. What makes WhatsApp so special is its simplicity and ease of use. You just open up the app and start chatting without the worry about international calling rates or SMS charges..

The app has had a major impact on personal and professional communications. Many businesses now use WhatsApp to communicate with customers, clients and employees. There is some worry, of course, that the app could be used to share sensitive information that could be accessed by others. But it offers end to end encryption, and its speed overrides such concerns. No waiting for a text message reply or an email response.

WhatsApp is now transitioning into a Super App, where it is offering entertainment, mobile payments and e-commerce in addition to messaging. WhatsApp was sold to Facebook in 2014 for $19 billion, but continues to operate as a separate app. It was founded in 2009 by Jan Koum and Brian Acton, two former employees of Yahoo.
