The first, the best one, a wonder if.... it was able to open tif files as said in presentation but it cannot. An impressive lot of option but... missing a thing: an option "see on map" to display geolocalisation on a map (Google or any other like Osmand, for instance) of pictures owning these data into exif file for photographs and backpackers.... I wish into next update. Dear developers, FELICITATIONS... For your information, it exists an app reading correctly tif files (FIV app) and owning option "see on map" which presents a bug. I've contacted its developer but this app is today discontinued... So, go ahead and Perfect Viewer will become Ultra Perfect Viewer, the only one really perfect. Regards.
