FaceTime

If your parents or grandparents haven’t had their iPhones for long enough, they might not have tried FaceTime yet. Even though it’s a pretty simple app, FaceTime is the perfect tool to stay in touch with all your friends and family.
FaceTime really needs no introduction; this video calling app lets you talk to any one of your contacts who also has an Apple device. You can call and start talking to them instantly. You can have video calls, or turn off your camera and have a regular phone call.
While the FaceTime app works best with Apple devices, you can talk to anyone, no matter which device they have. You can share call links with Android or Windows users and have video calls almost instantly.
