iCaelum 2.6.0

iCaelum brings weather, the Sun and Moon, and outdoor planning into one app. Get a clear answer for today, then open the details you need.

TODAY, AT A GLANCE
Your weather, daylight and Moon, with three simple doors: Weather, Sun and Moon, and Activities. Pin the activities you use most to keep them on Today.

MY VIEW, YOUR OWN MIX
Create one personal view with up to eight features from across iCaelum. Combine Photography's Shadow calculator, Fishing and hunting's Tides, and Weather's Forecast or Wind in one place. Name your view, arrange its features and pin it to Today. My view has its own graphite, bronze and jade background.

MAKE EACH ACTIVITY YOURS
Reorder or hide sections in the ten activity profiles, and add up to eight extra sections from the rest of the app. Save a separate layout for each profile. Remove additions you no longer need, or use Reset view to restore the original sections and order. Other views also offer section ordering, hiding and reset where available.

ANY PLACE, ITS OWN TIME
Use your location or choose a place by searching, dropping a pin or entering coordinates. Weather and planning screens follow that place, with times shown on its local clock. Live compass and camera tools use your phone's position and heading.

WEATHER
An hourly forecast, a 48-hour temperature and rain ribbon, daily outlooks and an AI summary of the next 24 hours. iCaelum selects national weather services where available, including the U.S. National Weather Service, SMHI, FMI, Hong Kong Observatory and Taiwan's Central Weather Administration, with Yr from MET Norway elsewhere. Compare with Open-Meteo, WeatherAPI or OpenWeather.

Explore rain radar and wind maps, air quality, UV and pollen, official MeteoAlarm warnings and personal alerts.

SKY FINDER
Point your camera at the sky to find the Sun, Moon, seven planets and stars. Switch layers, search an alphabetical catalogue and follow directions to your chosen object. More than 5,000 stars are calculated offline on your phone. Clear marker centres leave the sky visible; manual alignment helps you match a familiar object. The live camera uses your physical location and the current time. Compass accuracy and observing conditions affect what you can see.

SUN AND MOON
• Today's sky, positions, rise, transit and set times
• A year ribbon and full-year almanacs
• Golden and blue hours, twilight and both solstices
• Upcoming solar and lunar eclipses for your chosen place
• A 2D sky chart and AR viewfinder to help find the Sun or Moon
• Shadow length and direction for any object, place and time, with a chart that scales to fit

TEN ACTIVITIES
• Photography: golden and blue hours, a light dial, shadows and a time-lapse planner
• Stargazing: Sky finder, darkness, sky quality, planets, meteor showers, aurora and clouds
• Beach: UV, shade, live shadows and sunscreen reminders
• Gardening: planting by the Moon, frost risk, sunlight and solar energy
• Hiking: daylight left, route exposure, campsite light and an offline SOS signal
• Fishing and hunting: solunar feeding periods, tides, wind and weather
• Sunlight and shade: sun paths, building shade, facade sunlight and solar energy
• Events: save plans with their own place and hours, forecasts, tides, light, shade, templates, shared links, QR codes and calendar export
• Sailing: compass bearings, wind, tides, celestial sights, navigation stars and current-aware passages
• Night running: when you need lights, mapped lighting, visibility and surface conditions

EVENT WIDGETS
Follow one event, your next event or a list of upcoming events on the Home Screen or Lock Screen, with up to four values for their hours, such as wind, rain, temperature, sunset and sea conditions.

Every screen includes a guide to its colours, symbols and figures. Choose your weather units; Sailing also offers knots, km/h and m/s.

iCaelum calculates the Sun and Moon on your device and gets weather, air and tide data through its own service. No account is needed.
