If you're looking for ways to streamline communication with your bandmates, onstage and off, you might want to take a look at BandHelper. (I'm not affiliated with BandHelper, but the developer recently posted about 1Chart on his site, so I thought I could return the favor here.)

BandHelper is designed to help corral all the info bands need to organize performances, from set lists to booking contacts, event reminders, etc. And it includes support for backing tracks and other on-stage tools.
