I am wanting an app for iPad and iPhone, which is essentially a world map with different event pins displayed around the globe. Users of the app would be able to perform filters to display different event based on the filters. In the backend there needs to be a facility to administer the various events, with the ability to permission this access to key users. I.e. Event planners can add in events themselves.
In the front end app a user will add various events to their profile and them see them in a calendar view. It would be also great if users could see other selected users events...I.e. Friends events
Look and feel would be similar to the [url removed, login to view] iPad app....map based with filters.
I am wanting to know the rough costs of such an app.
I work in it so can put together a more detailed functional spec, but need to know cost of creating such an app.
