Asterfold shows the Sun's path across a sky dome for any place and date, coloured by golden hour, blue hour and twilight. Scrub through the day to see the Sun's altitude, bearing and shadow length, then save a shooting spot.
Pick a lens from 14 mm to 200 mm and Asterfold shows the dates this year when the Sun sets or rises inside your frame. The Tonight view rates the sunset, stars and sunrise with hour-by-hour cloud data from MET Norway. The sun path is calculated on your iPhone, so it works offline.
