Instead of having a separate calander, spreadsheets and chat all over the place, with different accounts, use Band Mule to do it all in one app. Three taps is the most you'll ever have to do to find the information you're looking for.
Drop a note here about a gig, practice or setlist and everyone knows exactly where to look.
Get notified with mobile notifications. As with calendar updates, new messages will be sent to your phone as a push notification so you'll never miss an update.
Not only does Band Mule have an iPhone and Android app, there is also the desktop app you can use via a web broswer.
Everything is there, from chat, to setlist management, to calender updates.
