Event Operations App - for use at Festivals and large Sporting events

The app is used by staff and volunteers employed at large outdoor events.

The app is mainly used outdoors, to communicate with the users who are employed by an event. Think of the road marshals directing traffic, security people at gates, helpful volunteers giving directions, etc. Because it's mainly outdoors, graphics need to be bold and clear, and buttons larger than normal, to allow for sunlight (and rain!).
