Description

This app is an alarm that notifies at dawn, sunrise, sunset and dusk. If you would like to begin activities 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 the 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 is 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.

Grateful for this app

This app is very helpful. I don't know any other app that works this well. Thank you for making improvements. If I was able to choose the days that I want the the alarm to go off then that would be perfect.

Respect to the author

I use it for yoga meditation in brahma muhurta time. Thanks a lot for this app.
It is very easy to settle local time and choose a pleasant sound for alarm.
For a month it never failed to ring me up. 👍🏻🙏🏼
