DaylightGraph

See a full year of sunrise and sunset, at a glance — as a graph. Plenty of apps can tell you what time the sun rises today, but surprisingly few show you how that time changes over the course of a year. DaylightGraph plots a city's sunrise and sunset times as a simple line graph, so you can see the whole year's pattern at once. ■ Features - Just type a city name — latitude, longitude, and time zone are found automatically - Graph sunrise and sunset times over any period, up to a full year - Also shows civil twilight and solar noon altitude (how high the sun climbs at midday) - Pinch or use the +/− buttons to zoom in on a specific date or time - Compare daylight across multiple cities, overlaid on the same graph - Analyze custom conditions, like "how long does sunrise stay later than 6 AM?" - Automatically detects and displays the midnight sun and polar night at high latitudes - Supports countries and regions that observe Daylight Saving Time, with DST periods clearly marked ■ Who it's for - Anyone checking how daylight hours change before a trip or business trip - Photographers tracking golden hour and other seasonal lighting changes - Anyone simply curious about the sun's yearly rhythm Available on iPhone, iPad, and Mac.
