Problem. You have found a nice new apartment to live in. However, you still don't know how much sunlight is entering through the windows, how much is getting into the balcony or the terrace.  You want to know how many hours a day, and which days during the year the sunlight will get into the place.

 

Concept. With easySun you will be able to turn your device into a "sunlight predictor".  Just point the device in the same direction as the window (balcony or terrace) and easySun will give you a report of the amount of sunlight reaching the place.

 

Requirements. easySun is a lightweight application with minimal technical requirements.  It works better in devices having an internal compass.  However, it still works in devices without compass but the user have to set the direction of the window manually.

 

Latest version. beta 3.7 (25 March 2016)

 

What's new: We have improved considerably the
model to calculate illumination.  Now the app take

into account the effect of atmospheric attenuation

and time of day.
