In the area of text messaging Whatsapp the undisputed number one. Many are not aware that the application can do more than just exchange messages. Founded in 2009 and owned by Facebook the chat app with the green logo has become familiar to every smartphone owner.
Users of the free application must register with the service using their mobile phone number. After verification via SMS code, the account is active. While Whatsapp is available on some platforms, the app offer leaves something to be desired.
Owners of an Android or iOS smartphone can use the chat app in most cases as normal. It becomes more difficult if without Smartphone to be chatted. iPad owners have no option Whatsapp install natively. And also with one Android tablet let yourself Whatsapp not always use. On PC and Mac there is a web application, but with the Smartphone must be coupled and cannot act alone. In this there are no language or Video calls possible.
On the Smartphone yourself Video calls start in no time. Once in the chat window of the desired contact, you can start using the camera symbol in the top right corner. The connection establishment is almost without delay even with a bad connection. The quality of the Video calls depends heavily on the bandwidth and fluctuates massively. Although video chats are possible even with slow performance, in most cases more than one pixel mash will not be possible.
Video calls via Whatsapp are encrypted end-to-end. While the encryption implemented in collaboration with Open Whisper Systems is considered strong in itself, security researchers at least have doubts as to how complete it is.
Whatsapp is available free of charge for iOS and Android.
