Hello, A new app, GnomonicPhoto, is available on Google Play, which allows you to take pictures of sundials while viewing the true solar time on the smartphone screen.
This information, together with another information of gnomonical interest, can be added to the photograph for later study or archiving. http://www.tempusumbra.byethost3.com/gnomonicphoto/PromoDoc/GnomonicPhoto_EN.pdf https://play.google.com/store/apps/details?id=com.tempusumbra.gnomonicphoto -- César Busto
