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.

http://SunTrajectory.net allows you to display the future trajectories of the sun in augmented reality:
* Look through your phone and see the path of the sun.
* 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.
Moon Path is included:
* No need to have both apps installed on your phone.
* You can browse the trajectories of the sun, its shadow and also of the moon on the same photos!
* Find out if the moon will be full or what phase it will be in.
* For more details, please visit the website of
* 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.
* Plan when the sun will light a scene (and not be hidden by a mountain or a building).
* Imagine the outline of shadows on the scene at a later date.
* Use the agenda to plan your future pictures.
* This way, you will know when to return to the site to take your picture to the maximum effect.
* Use Google Maps to pinpoint its exact location.
Justification of the authorizations required by the app:
* Modify/delete USB storage contents modify/delete SD card contents
Photos are saved on the SD card.
* Coarse (network-based) location / fine (GPS) location
The app requires your location to compute the trajectories.
* Prevent device from sleeping

* Full Internet access
Used by GoogleMaps only.
* Take pictures and videos
The app takes pictures and displays video.
2.7: You can now predict where the sun will be… if reflected in water!
2.6: If your phone is equipped with gyroscopic sensors, the application uses them in order to further improve the image stabilization.
2.4: Image stabilization has been improved, so using the app will be more comfortable. Feel free to post comments on the Facebook page of the application!
