Sunrise and sunset time predictions have limited accuracy, especially in the northern latitudes, due to refraction in the atmosphere. To improve the models, we need observations of sunrises and sunsets from various locations around the globe.
This app allows you to take observations even while offline and submit them when you have a wifi connection.
