Golden Hour Calculator is an iPhone application developed by Christopher Kreymborg. It is a free multimedia program designed to help photographers find the perfect time for photography every day, everywhere.

With Golden Hour Calculator, users can easily access the exact timings of magic hour times, including golden hour, blue hour, sunset, and sunrise. The app provides accurate data for the user's current location and date, ensuring that photographers never miss that perfect light for their photography again.

One of the standout features of Golden Hour Calculator is the ability to set up notifications. Users can choose to receive notifications for golden hour, blue hour, sunset, or sunrise, and customize how long before they want to be notified. This ensures that photographers are always prepared and can make the most of the optimal lighting conditions.

Additionally, the app allows users to save their favorite places as bookmarks for quick and easy access to magic hour times. This is particularly useful for photographers who frequently need to look up magic hour times for specific locations.

Overall, Golden Hour Calculator is a reliable companion for photographers, providing accurate and timely information about the best times for photography. While the free version offers basic features for the user's current location and date, upgrading to the plus-version unlocks additional features such as a date and location chooser, notifications, and bookmarks.
