About SolCalc - Solar Calculator
SolCalc is a sun and moon calculator that tells you when the light will be right — at any place on Earth, on any day you pick.
Get sunrise, sunset and solar noon together with data of the blue hour, the golden hour and the twilight times (civil, nautical and astronomical). Calculate moonrise, moonset and moon phases (calculated data are approximations of +/- 1 day accuracy). You can also calculate and visualize the shadow length that an object will create.
Point your camera at the scene and AR mode draws the sun's path straight onto the live view, with golden hour and blue hour markers, azimuth, elevation and shadow length.
A widget puts the next golden hour, sunset or blue hour on your home screen, and reminders tell you before the light changes — calculated on your phone, without an account or a server.
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.

Wear OS app with tile and complications
⌚ Day ring: a 24-hour dial shows night, twilight, golden hour and daylight around the clock, with the next sunrise, sunset or blue hour and a live countdown in the middle.
📋 Today's times at a glance – sunrise, solar noon, golden hour, sunset and blue hour, plus the twilight phases you choose in the phone app – and the moon phase with moonrise, moonset and their direction.
📍 Locations sync from your phone, or use the watch's own GPS. Always-on display supported.
🧩 Tile: swipe from your watch face to the SolCalc tile for today's sunrise, sunset and day length at your selected location.
⏱️ Complications: put SolCalc data right on your watch face – the next sunrise or sunset, a daylight gauge showing how much of the day is left, the next golden or blue hour with a live countdown, and the moon phase with the next moonrise or moonset.
