Create set lists and share them with your band members! Use the live mode to see the current song's info on stage or at rehearsals and switch to the next song by MIDI or manually:

Enter all your songs, set lists and performances, and in 'live' mode 'play back' your performance: in this mode, the song title, artist, the next song, settings for the current song (like patch/preset numbers, key, whatever), and other notes are displayed. Besides that, if you have entered (or tapped) a tempo, this will show as a blinking bar as well! Very easy if you have to start a song.
Each line's text can be configured with a different font size.
Switching to the next song can either be done manually or by MIDI control changes. Note that the MIDI part requires Android 3.2 or higher, a device that supports USB host mode and a USB MIDI interface that doesn't require drivers under Windows. Basically, if it works with my free USB MIDI Monitor app, it will work with this one.
Runs best on tablets, but you can use it on phones too.
Enjoy!
