Version 2.2 for iOS adds a new module to build stage plots for your band. This functionality is also available as a standalone app called Stage Plot Maker. I made a demo video for the standalone app, but everything you see here is also available in BandHelper:

On that page, you can enter a display name and upload a photo, and then that user will be available to add to the stage plot.
This functionality will be added to the Android app in a future version.
