Built for photographers, made for anyone who loves good light. Pick any place and any date, and SunWindow lays out the whole day: golden hour, blue hour, civil, nautical and astronomical twilight, sunrise, sunset and true night — all computed on your device in seconds. **THE DAY AT A GLANCE** - A single wheel showing every light phase from dawn to dark - Full times table with every transition - Live countdown to the next window **SEE WHERE THE SUN WILL BE** - Sun rays drawn directly on the map - Elevation and azimuth for any moment - Drag the pin anywhere — the whole day recalculates instantly **PLAN THE WHOLE YEAR** - Year chart showing how your light shifts season to season - Find the date when the sun lines up with your shot **NEVER MISS THE LIGHT** - Bell reminders on any phase - Set your own lead time so you arrive early, not late **MADE TO BE LIVED IN** - Background colors shift with the sky - No accounts. No ads. No tracking. **A note on accuracy** SunWindow is a planning guide, not a navigation instrument. Times are computed with standard astronomical algorithms and are accurate to well under a minute for planning purposes, but local terrain, horizon obstructions and atmospheric conditions will shift what you actually see.
