## What is 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.
