Instruments
25 time, weather, and environmental studies: local conditions, sky, calendars, world time, and functional visual experiments. Native apps may adapt them into full views, device widgets, Tiles, or complications when each surface can preserve their meaning.
Celestial
Quiet sky, sun, moon, and tide displays that compute the light and water where you actually are: the year-long analemma, the sun's daily arc, the moon's track, the day and night line crossing a turning globe.
Weather
Live local conditions, read from Open-Meteo (and NOAA for the tide) and failing soft to cached data: temperature, wind, rain, cloud, humidity, pressure, and the UV and air-quality screens.
