AirPlay - Cast to Tv appears to be an Android app that allows users to cast the content of an Android smartphone to a TV or another compatible screen. In addition to supporting the Google Cast protocol (used to cast content from Android devices to TVs compatible with Chromecast), the app also supports Apple AirPlay (for casting content from Apple devices to other AirPlay-compatible devices), as well as the DLNA protocol (which is used for media sharing between devices on a local network).

This allows users to Cast Screen a variety of content such as:

Web videos: The ability to stream videos from apps or browsers to a TV.
Music: Streaming music stored or streamed from the phone to the screen.
Movies: Watching movies from an Android smartphone on a larger screen.
Games: Playing games on the phone while casting the screen to a TV.
Photos: Displaying photos on a bigger screen.
This app seems to aim for maximum flexibility by supporting these three widely adopted protocols (AirPlay, Google Cast, and DLNA), making it easier to cast content between devices. It can be particularly useful for Android users who want to cast content to TVs or screens that may not necessarily be compatible with Chromecast or AirPlay.
