Mirlow is a free screen mirroring application for Windows 10 and 11 that allows users to display the screen of an iPhone, iPad, or Android phone on a PC over a Wi-Fi connection. The application functions as both an AirPlay receiver and a Miracast receiver, enabling wireless mirroring without requiring users to install an app on their phone, create an account, or use a cable. The software is open source, with its code publicly available for review and verification. The primary workflow involves opening Mirlow on a Windows PC, which makes the computer discoverable on the local network. On an iPhone or iPad, users access the Screen Mirroring option in Control Centre; on Android devices, they use Smart View, Cast, or Wireless display settings, then select the PC from the list. The phone screen then appears on the PC, with audio routed through the computer's speakers in sync with the picture. Users can toggle full screen mode with a single key, and the display adapts to both portrait and landscape orientations. Key features include wireless mirroring for AirPlay-compatible devices (iPhone, iPad, Mac) and Miracast-compatible Android devices, audio transmission, full screen display, and privacy by design. All data remains on the user's local network, with no servers, accounts, or tracking involved. The application is free without trials, watermarks, or subscriptions, and its open source nature allows anyone to inspect the code, build it independently, and confirm that the downloaded version matches the published source.
