When a song is playing in Apple Music app, this app displays the custom lyrics saved in the local media of the song. As Apple Music app plays the next track, this app automatically displays the lyrics of the next track. This is particularly useful if you sync your large iTunes library with lots of custom lyrics. Please note that this app does not display lyrics of any songs from any streaming services, nor does it retrieve lyrics from the Internet, only the song lyrics saved locally in Apple Music app. Apple Music app can display lyrics. However, in my own case, it only works for some songs. Somehow, most songs don't show lyrics. I haven't been able to find a fix for this, so I wrote this app and have found it very useful for myself. You can change the font size of the lyrics for the best viewing condition. You can view in portrait mode or in landscape mode.
