However, as FaceTime doesn’t run on Android phones or tablets, WhatsApp is ideal if you want to communicate with someone who isn’t using an Apple device. iPhone owners can do this already with users of other iPhones, iPads and Mac computers using FaceTime. It allows you to send messages, pictures, videos and even voice recordings, and to make voice and video calls over the internet for free, rather than paying to do the same using your mobile network.
WhatsApp is a free app for iPhones, Android smartphones, Macs and Windows PCs.
