MobileForge is a free pattern generator app for iOS, Android, and Fire TV devices. MobileForge generates accurate test patterns automatically on your mobile device, controlled by CalMAN
The 2nd generation or later Apple TV can be used to accurately transfer grayscale and color test patterns from an Apple mobile device to a TV to be calibrated, using AirPlay Mirroring.
With MobileForge installed on a Fire TV Stick or on a Fire TV Box, the MobileForge test patterns can be fed directly to an HDMI input of a TV or monitor.
You can cast your Android screen (running Android 4.4.2 or higher) to a Google Chromecast, Chromecast Ultra, or TV with built-in Chromecast.
