Yes, the projector supports Airplay via the AirScreen app. To do this, you must install the AirScreen app on the device and connect both devices to the same Wi-Fi network. The official instructions confirm that XGIMI products such as the HORIZON provide Airplay functions via this method.

Note: The above steps apply to the HORIZON - for your "Horizon (Full HD)" model, the exact procedure may vary, but Airplay functionality is typically available via AirScreen on XGIMI products in this series. If you are unsure, I recommend taking a look at the instructions supplied or the manufacturer's support portal.
