Suntimes
Android app (and widget collection) that displays sunlight and moonlight times for a given location.
Displays sunrise and sunset, twilights (civil / nautical / astronomical), blue and golden hour, solstices and equinoxes, moonrise and moonset, moon phases and illumination.
An alarm clock for Suntimes.
A calendar provider add-on for Suntimes.
A hunting and fishing add-on for Suntimes.
A 24-hour clock & roman timekeeping add-on for Suntimes.
The app:
- displays the current time (system time zone, custom time zone, or solar time)
- displays the time until the next rising/setting event.
- displays the sunrise and sunset, blue and golden hour, and twilight times (civil / nautical / astronomical).
- displays the current moon phase, illumination, moonrise and moonset times, and major phase dates.
- displays the current sunlight and moonlight projected over a world map (basic equirectangular, blue marble).
- displays the solstices and equinoxes, and notes the time until the next event.
- displays the sun's current position, and its position at sunrise, sunset, and noon.
- displays the moon's current position, and its position at moonrise and moonset.
- includes an Alarm Clock that can set a repeating alarm or notification for the next sunrise or sunset (or other rising/setting event).
- can display the configured location on a map (requires a map application) and configure the location from a map (using geo intent).
The app:
- does not require GPS. The location is manually specified by default (and optionally obtained from GPS).
- does not require network connectivity (or other unnecessary permissions). All calculations are performed locally on the device.
Widgets are (re)configurable:
- location (latitude, longitude, elevation).
- time zone (system / custom), sidereal time (lmst, gmst), or solar time (local mean time, apparent solar time).
- user-defined titles (supporting limited substitutions).
- misc. options: "use elevation", "show seconds", "show noon", and "show comparison", etc.
Widgets are themeable and provide:
- a theme editor and support for basic custom themes.
- a (default) dark theme (and dark w/ semi-transparent background).
- a (default) light theme (and light w/ transparent background).
Widgets are resizable and include...

- 1x1 digital clock widget that displays solar time (or a given timezone).

- 1x1 sun widget that displays the sunrise or sunset time.
- 1x1 sun widget that displays both sunrise and sunset times.
