SunriseSunset times is a free iPhone application developed by Sergio Arroyo Val. This utility app provides users with precise information about the exact times of sunrise and sunset at their current location and other useful details about the sun and the moon. It also offers the ability to retrieve information for different locations and dates, whether in the past or future.

With SunriseSunset times, users can access the following information:

• Sunrise and sunset times for every day.
• Time of local solar midday.
• Date and time of lunar phases.
• Date and time of the start of the seasons.
• Date and time of winter and summer time changes.

The app also offers additional features, including the ability to browse information for any specific date, the option to use the device's current location or select any other location on the world map, and the capability to display times according to different time zones if the selected location differs from the device's time zone. Moreover, the app accurately handles polar regions, where the sun may not rise or set for extended periods.

Additionally, SunriseSunset times includes a convenient widget that allows users to view today's data directly on their lock screen, providing quick access to essential information without unlocking their device.
