LyricCast

LyricCast is an Android application that allows you to cast lyrics to your TV screen using Google Cast. The main audience for the app is churches, where the lyrics are projected on the screen during the service. Current solutions require proprietary hardware and software which are expensive and often slow responding. LyricCast aims to provide a simple and affordable solution for churches and other organizations that need to cast lyrics to a TV screen using off the shelf devices. LyricCast is localized in English and Polish.
