Blue Hour is a tool for photographers, that calculates information about sunrise, sunset together with data of the blue hour and the golden hour. Furthermore you can calculate information about moonrise, moonset and moon phases (calculated data are approximations of +/- 1 day accuracy).

In this app you can view sun-data of multiple locations. These can be defined manually or automatically by getting your GPS- or network location. Furthermore it is possible to add reminder for the events, that you do not miss them. Additionally you have the opportunity to manually set timezones of the locations, which can be helpful if you are planning trips to locations with another timezone than the one, where you currently are in.
