WhatsApp Messenger, or simply WhatsApp, allows users to send text messages and voice messages, make voice and video calls, and share images, documents, user locations, and other content.
It was founded in 2009 by Jan Koum and Brian Acton who had previously spent 20 years combined at Yahoo. WhatsApp joined Facebook in 2014 ($19B purchased), but continues to operate as a separate app with a laser focus on building a messaging service that works fast and reliably anywhere in the world.
Your personal messages and calls to friends and family are end-to-end encrypted. No one outside of your chats, not even WhatsApp, can read or listen to them.
All you need is your phone number, no user names or logins. You can quickly view your contacts who are on WhatsApp and start messaging.
Make secure video and voice calls with up to 8 people for free*. Your calls work across mobile devices using your phone’s Internet service, even on slow connections.
Stay in touch with your friends and family. End-to-end encrypted group chats let you share messages, photos, videos and documents across mobile and desktop.
