What is the purpose of the FaceTime app?

The FaceTime app is primarily designed for making video calls, enabling users to connect visually with others through their Apple devices. This service allows for face-to-face communication over the internet, making conversations more personal and engaging compared to traditional voice calls. FaceTime uses both front and rear cameras, and users can switch between the two during a call, enhancing the overall experience. It integrates seamlessly with the Apple ecosystem, allowing users to easily connect with friends and family who are also using Apple products.

The other options do not accurately describe the FaceTime application's function; it does not send text messages, organize photos, or provide navigation services, which are specific to different apps.
