This app is an alarm which notifies at dawn, sunrise, sunset and dusk. If you would like to begin activity soon after sunrise, the app is most suitable. The app can confirm sunrise, sunset, dawn and dusk on a current position and main cities immediately. And you can check time of the dawn, the dusk, the sunrise and the sunset even if you do not allow local notifications.
The app is using Japanese dawn and dusk which established by a samurai (a shogunate employee), but there are almost the same civil twilight. The civil twilight begins and ends when the geometric center of the sun is 6° below the horizon. However, the dawn begins and the dusk ends when the geometric center of the sun is 7.3611° below the horizon. If turn on the civil twilight switch, the dawn and the dusk will be civil dawn and civil dusk.
