Sol: Sun Clock


How many more hours of sunlight remain in the day?

Have you ever wanted to know exactly when the sun will rise or set or know exactly when the sun will be at its peak? This app for iOS will tell you that and more.

The interface is easy to understand and includes data such as sunrise/sunset times and durations and days from/to the last/next solar equinox or solstice. It will determine your current location by default, but you can calculate times for any location on the planet.

The nicest feature is being able to set alarms for certain solar events. I like using sunlight as much as possible and have come to rely on this app as a poor man’s curtain timer. I have set an alarm at sunrise and sunset so that I know when it’s time to open or close the curtains around the house. It changes slightly everyday, but stays in sync with the sun. Photographers will find the golden hour alarm setting useful for knowing the best time for taking outdoor photos.

It’s also interesting to see how much daylight saving time and choice of time zone have skewed the traditional notion of noon (solar noon). I live in Indiana (geographically in the Central Time Zone, but most of the state observes Eastern Time) and during the summer months, solar noon is almost 2 hours later than noon by the clock. (WTF Indiana?!)

While several weather apps now include sunrise and sunset times, the features offered by this app make it it well worth the price.
