Key Features
Profiles
Tailor iCaelum to your needs with predefined profiles. Whether you want to capture golden hour, plan a sailing trip, or follow lunar cycles, the app highlights only the most relevant data for your activity.
Forecasts
Compare conditions from multiple trusted sources, including OpenWeatherMap, Yr, Open-Meteo, FMI, SMHI, and DMI. Get side-by-side predictions for temperature, precipitation, cloud cover, and visibility to make informed outdoor decisions.
Sentinel
Stay safe outdoors with real-time environmental monitoring. Sentinel tracks weather conditions, air quality, UV radiation, pollen levels, and natural disaster alerts—delivering safety indexes, live threshold notifications, and color-coded risk levels so you always know when to take action.
Trackers
Follow the live position of the sun and moon with real-time updates. Receive notifications for sunrise, sunset, moonrise, moonset, and twilight phases, and track how light and shadows evolve throughout the day.
Celestial Data
Access detailed almanacs with historical and future information on sun and moon phases, rise and set times, twilight periods, and seasonal variations. Generate reports for any date and location to plan long-term projects or explore celestial patterns.
Shadows
Calculate and visualize shadow lengths and directions for any object or location. A powerful tool for architects, urban planners, and designers who need to understand light and shade across seasons.
Winds
Explore global wind patterns with live flow maps. View speeds, directions, gusts, and upper-level streams in real time—an essential feature for aviation, sailing, and outdoor sports.
Rain Radar
Track approaching storms and precipitation with live rain radar reports from external providers, giving you real-time visual maps to anticipate sudden weather changes and plan with confidence.
Ratings & Reviews

Upcoming Eclipses has been rebuilt around a proper astronomical calculation.
• Eclipse times are now computed for your exact location rather than
estimated, and the timeline always reads correctly from start through
maximum to end. Before, an eclipse that set below the horizon partway
through could show the same time for both maximum and end.
• Each eclipse card shows more of what is actually happening: the umbral
phase of a lunar eclipse, the totality or annularity window of a solar
one, the hours the Sun or Moon is above your horizon, and — when the
deepest phase falls after it has set — the best moment you can still see.
• Descriptions now explain what the eclipse looks like from where you are,
including when it is grander elsewhere along its track.
• Fixed the pollen peak countdown showing "in 0 days" for a peak due
tomorrow.
