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, moonset, lunar noon, lunar midnight, apogee, perigee, and major phase dates.
• displays the current sunlight and moonlight projected over a world map (basic equirectangular, blue marble, or azimuthal maps).
• displays the total amount of sunlight over the year, and earliest/latest sunrise and sunset times.
• displays the solstices, equinoxes, and cross-quarter days, 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 support for custom rising/setting events; the time when the sun is at a given angle, or an object casts a shadow of given length.
• includes an Alarm Clock that can set a repeating alarm or notification for the next sunrise or sunset (or other rising/setting event).
• includes a "Quick Settings" tile that displays information as part of the settings tray.
• 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.

The alarm clock:

• supports different types; schedule "alarms", "notifications", or "quick notifications".
• supports astronomical events (in addition to ordinary alarms), and repeating alarms that are rescheduled as event times change throughout the year.
• includes features for heavy sleepers; challenges to dismiss alarms ("easy math"), snooze limits, and bright fullscreen alarms.
• includes a bedtime mode that schedules alarms using sleep cycles, and manages do-not-disturb during sleep hours.

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).
