We all know that this one to be the most popular among many. This Apple Face Time allows a user’s to make both audio and video calls with up to 32 total people. The little downside of this is that for it to work, all participants must use iOS devices which can be iPhone, iPad, iPod Touch or Apple Watch and Mac. This is to say those using Android and Windows will not use FaceTime.


This is another great app to make conference calls. This app has been around and it supports both Audio and video calls as well. You can also use the app to read and reply to messages. For some reason, some of this App is not available for those in UAE. If you stay in Dubai, you can check out our list of App you can use to make video calls in UAE.
