“Launched in 2009, WhatsApp is a free, multi-platform messaging app that lets users make video and voice calls, send text messages, share their status, and more with just a Wi-Fi connection.”– Digital Trends
What makes this app appealing is that it works on various phone and computer operating systems, so you can continue your conversation anytime, anywhere. It can also take advantage of Wi-Fi and cellular data to make one-on-one or group calls, reducing the need for expensive calling charges.
WhatsApp uses your phone’s cellular or Wi-Fi connection to facilitate messaging and voice calling to nearly anyone on the planet, alone or in a group, and is especially nice for families and small collaborative workgroups. The app lets you make calls, send and receive messages, and share documents, photos, and videos. WhatsApp is completely free — with no fees or subscriptions
