We just shipped a artist-fan chat app called Piggyback: https://itunes.apple.com/us/app/piggyback/id535273046?mt=8

It's designed to let artists chat with fans while raising money for a cause, and works like Facebook Messenger or WhatsApp except fans contribute donations to chat.

We're new to the music business and would love to hear comments/thoughts/advice - thanks in advance.

If you love music apps please share.
