Welcome to!
This app will enable you to visualize
where the sun and the moon will run
their courses while watching through
your phone.
You can now plan:
Where and when the sun will rise or
When it will be hidden by a building
or a relief.
When it will be seen according to a
specific axis/angle.
+Same thing for the moon!
* If, for example, you're visiting a
house you wish to buy, take a lot of
pictures with the application.
You will then be able to visualize the
sunshine at different moments of the
Shoot the inside from a window, and

using the calendar.
Use the "now" button to get back
quickly to the present date and time
* The blue arrows represent the
summer and winter solstices. The sun
path will always be -all year long-
between those two.
This way, you can immediately see
that the sun on this picture will never
be lower than the blue arrows.
This is also relevant for the drawing
of the shadow.
Choose between displaying the sun,
its shadow, or the moon.
The drawing of the shadow can help
you predict where your own shadow
will be.
If you are at the top of a building or a
mountain, you will then be able to
predict its shadow!
Use the moon phases calendar:
Learn at a glance on which days the
moon will be full (or conversely when
the night will be moonless).
The upper-left drawing shows
precisely which phase of the moon
you will see on the chosen date.
