Cast to TV is a free screen mirroring app for Android that allows you to mirror your smartphone's screen and audio to a larger TV screen. The app uses your phone's built-in microphone and speakers to broadcast the sound to the TV. The sound is also broadcast to the mirroring phone, so it can be used to stream audio to the TV as well.

The app is compatible with many TV models and can be used with an Android phone. It also supports many popular media players and streaming services, including Netflix, Hulu, Vudu, DirecTV, Xfinity, HBO, and many more.

If you want to use the app, you need to install it on your phone first. After that, you can connect your phone and TV to the same Wi-Fi network, select the TV you want to mirror, and start streaming to it.

The app will automatically detect the connection and mirroring status of your device. You can also check the connection status of your device by going to the Settings menu of the Android phone.
