With over a billion users, Whatsapp, owned by Facebook, is one of the most widely used free messaging apps.
It runs on a wide range of smartphones. You can send messages, photos, documents and make audio or video calls (including international connections), to single or groups of contacts.
It operates over the Internet, so it's free to use over wifi and uses your data allowance when you're not on wifi.
Whatsapp is usually used to send messages to a defined contact group, and it allows the sender to see who has received a message and who has read the message.
