AirPlay - Cast Screen is a versatile application that enables users to wirelessly mirror their device's screen onto compatible displays such as TVs or projectors. It operates by establishing a connection over a shared Wi-Fi network, allowing users to display videos, photos, presentations, and more. This makes it suitable for both personal and professional use.

While designed to work with a variety of devices, compatibility depends on the hardware and software versions. Most iOS devices with AirPlay and Android devices with casting features can utilize the app, but it is advisable to check the official compatibility list before downloading.

Primarily, AirPlay - Cast Screen uses a local Wi-Fi network for device connection, so an internet connection is not strictly necessary for basic screen mirroring. However, streaming online content such as videos or music requires a stable internet connection to ensure smooth playback.

The app prioritizes user privacy by not storing or transmitting personal data without consent. Nevertheless, users should connect to secure and trusted networks to prevent unauthorized access during screen mirroring sessions.

Common problems include connectivity issues and lag during mirroring. To fix these, ensure both devices are on the same stable Wi-Fi network. Restarting the app or devices can help. If issues continue, consult the app's support resources or contact customer support for assistance.
