SolarDial · for iPhone
Pick any place — or where you are standing — and SolarDial tells you when the sun rises and sets, when solar noon falls, and when the golden and blue hours begin and end. Every number is worked out on the iPhone.
Photographers mean slightly different things by them. SolarDial uses the sun's height above the horizon:
| Window | Sun's altitude |
|---|---|
| Golden hour | from 6° above the horizon to 4° below |
| Blue hour | from 4° below to 6° below |
There is one of each in the morning and one of each in the evening. Neither is really an hour: near the equator the sun drops through those bands quickly, while in winter and far from the equator it slides across the horizon at a shallow angle and the golden light lasts much longer.
Today, the Sun Dial and two saved places are free. SolarDial Pro, a one-time purchase, adds unlimited places, a shadow-length calculator and a daylight trend chart.
