FaceTime was launched in 2010 under the name of iSight Camera and it’s supported only on mobile devices running on iOS 7 an later, and by Macs running on OS X 10.9.2 and later. Skype is older, being released 12 years ago, and it can be installed on a variety of devices, but it is known that the quality of its voice and video calls is superior, because of the latest advanced codecs. Choosing between these two applications depends on two factors: their features and your friends. If your friends are using both of these applications, then you will need to get an iPhone, in order to call them.
As we told you in the introduction, FaceTime is Apple’s proprietary videotelephony product and it can be installed on an iPad, iPhone, iPod touch or Mac. Skype has versions for: Windows, Windows Phone 8 and 8.1, Xbox One, Mac, Linux, Android, iOS, Nokia X, Amazon Fire Phone, Amazon Kindle Fire HD/HDX, Amazon Fire HD Tablet, BlackBerry 10 , TVs and Blu-ray devices and PS Vita console.
The FaceTime users can make voice and video calls over Wi-Fi and 3G / 4G, and it’s not mandatory for the recipients to have a front camera on their devices. If they will receive a video call, they will only hear the voice of the person who makes the call. On Skype, the users can send text, photos, videos, create group chats and make group calls. They can also send instant messages and call landline and mobile numbers at low rates, but the users will need a Skype number.
Audio And Video Quality
The quality of the voice or video calls depends on: the type of connection (speed of the internet connection, if the device is connected to a wireless network or it uses the mobile data), the quality of hardware (microphone and camera), image processing and the compression used etc. Skype’s advantages are the Opus and SILK codecs for voice and the H.264 video codec and if the computers have a powerful processor and a strong internet connection, then the users will not experience any lags or interruptions during calls.
In November 2014, FaceTime had obtained a score of 5 out of 7 points on the Electronic Frontier Foundation’s secure messaging scorecard. This application benefits from end-to-end encryption. Skype had a few security problems and in November 2014, it scored 1 out of 7 on the same messaging scorecard.
