I created this app to accurately calculate light windows like Golden hour, blue hour, etc. for a particular city/location. It helps you plan your photography time by knowing the exact time and direction of sun. It uses swiss ephemeris on the backend to calculate all the path and timings for most accurate data.

It also has a 3D view of the sun's path on any day and at any point of the day for the location. Looking at the sun's direction and angle can help you plan your shoot correctly.

It is a simple app with no sign-in needed or any ads. Hopefully it helps folks out there. Open to feedback/request for features.

Considering an integration with weather APIs if this gains traction and people find it helpful
