SolCalc - Solar Calculator v1.4.8
Robert EhrhardtAbout this app
Developer Description
Easily plan & calculate photo and twilight times for the perfect shot!
This includes information about sunrise, sunset together with data of the blue hour, golden hour and twilight times (civil, nautical and astronomical). Furthermore you can calculate information about moonrise, moonset and moon phases (calculated data are approximations of +/- 1 day accuracy).
You also can calculate and visualize the shadow length that an object will create.
In this app you can view data for multiple locations. These can be defined manually or automatically by getting your GPS location. 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.
