02 / WAYS OF TIME
An hour isn’t
always an hour.
Your familiar clock is one way to read the day. SOLAR lets you discover three more.
The Sun keeps its own time.
On the solar clock, 12:00 is the moment the Sun crosses your local meridian. The same noon may have a different name on your ordinary clock.

IN AR
Sky and light score
Hold up your iPhone and follow the Sun and Moon across the whole sky. The light score is the share of the year’s direct sun that reaches your spot under a clear sky.
Object shadow
See where the shadow of an object falls, from the Sun’s calculated position.
Aim
Point at a landmark to find when the Sun or the Moon lines up with it.
AR needs a compatible iPhone, camera access and location permission. The light score assumes a clear sky; it is not a weather forecast.
These are app screenshots, not live calculations for your location. AR is a separate view on supported iPhones.
05 / FROM SOLAR LEARN
A little curiosity
changes the day.
Why is noon not always at twelve? Can an hour grow longer? Start with something you can see.

THREE MOMENTS, ONE DAY
You’ve read
a little of the sky.
In SOLAR, move through the hours and watch the light change at your own pace.
A FEW DETAILS
Before you
look up.
Why is solar time different from local time?
Local Time follows the selected place’s time zone. Solar Time follows the apparent Sun at that place. Its 12:00 marks the Sun’s passage across the local meridian.
Is this a live view of the sky above me?
The app calculates celestial positions for your selected place and time. The illustrated sky, clouds and sea are visualizations, not a camera feed or a promise of local weather. AR is a separate mode on supported iPhones.
Can I explore somewhere else?
Yes. Choose a place and date in the app to explore its solar day. The screenshots here use recorded views from Honolulu and Paris; they do not read your location.
Do I need an account?
SOLAR is designed without an account or advertising. Core solar calculations run on the device. Place search and optional weather features use external services, as explained in the privacy policy.
When can I download SOLAR?
