http://SunTrajectory.net enables you to predict the sun path and its shadow, simply looking through your phone.
Find sunrise and sunset times, not only on the horizon, but also depending on a building or a mountain.
The summer and winter solstices show the extreme positions of the sun over a year.
You can also predict the shadow, the sunlight in and out of a house, and even where the sun will be... if reflected in water!
Caution: some phones don't handle correctly gyroscopic sensors. Should you notice any innaccurate display, try deactivating gyros into application menu/settings.

* Plan the sunrise and sunset times, not only on the horizon, but also on a building or a relief.
* Travel in time and see what course the sun will follow in the months to come.
* The summer and winter solstices are displayed, showing the extreme positions of the sun over a year.
* Take and save photos.
* Check afterwards the different trajectories of the sun for a whole year.

* Visualize the sunlight in and out of a house you wish to buy for every month of the year.
* Predict the consequences of a shadow.
* Think about the orientation of a terrace, imagine creating a new window.
* Export your photos, including the drawing of the sun path, to your computer and integrate those pictures into a report (for example: photovoltaics).
* Plan your pictures according to the light effect you wish to create.
* Plan when a subject (like a statue for instance) will be lit from the angle you have chosen.
* Plan when that same subject will be aligned with the moon.
* Use the calendar of the moon phases.
