In Pensacola several community groups became frustrated with the difficulty of knowing what was happening in the community and more importantly the difficulty in finding a suitable time to schedule events that did not conflict with other events. Specifically those groups were the local veterans and the entrepreneurial ecosystem building group. Over the course of a few months of searching the web for options we found a solution from Germany - calendar.online. This met most of the criteria we were interested in, it was free for users, it had both IOS and Android apps and a good web interface with a usable planning calendar view.
This is such a great idea and hope more people and/or organizations start to utlize this.
