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.com 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 a saved event or your next event on the Home Screen or Lock Screen.

EarthSafe helps you know what to do before, during and after an earthquake. It is free, has no ads, and the parts you need most work without internet. KNOW WHAT IS SHAKING • Earthquakes from AFAD, EMSC and USGS in one list, with the place in your language, the depth, the distance and how strongly each was likely felt where you are • An archive back to 1900: the history of your area, the notable earthquakes, and what has shaken the spot you are standing on • The seismic globe: where the Earth shakes, what is shaking now, a century replayed, and the slabs beneath the surface filtered by years, magnitude and depth ALERTS THAT RESPECT YOUR ATTENTION • Notifications for earthquakes near you, not every earthquake on the planet. You choose the magnitude, the region and the agencies • After a strong earthquake nearby, EarthSafe asks "Are you OK?" so your family hears from you instead of guessing • EarthSafe is not an early-warning system: alerts arrive after an earthquake has been recorded YOUR FAMILY, IN ONE PLACE • Your family circle at a glance: who said they are safe, who needs help, who has not answered • Messages with one-tap replies ("I'm safe", "Stay where you are") and location sharing • Meeting points with directions, and a 60-second family drill WHEN SECONDS COUNT — WORKS OFFLINE • "I'm safe" and "I need help" in one tap • Drop, cover, hold on — indoors, outdoors, in a vehicle or in a high-rise • Torch, siren, messaging nearby phones over Bluetooth when networks are down, and a calm mode that guides your breathing and the next three steps PREPARE AT YOUR OWN PACE • A preparedness checklist that remembers the expiry dates in your kit • Your location risk: the distance to the nearest mapped fault, the last 30 days of earthquakes around you, and the largest on record nearby • Earthquake Captain: answers to nearly fifty safety questions — first aid, building safety, insurance, kits, what to do after — offline, and read aloud if you wish • A weekly preparedness quiz to play with your family ALSO • Home-screen widgets for your city and your readiness • Felt reports, aftershock curves, your seismic identity card, and the time machine: how a historic earthquake would shake you today • English, Turkish and Spanish Data: AFAD (Türkiye), EMSC (CC BY 4.0), USGS and ISC / ISC-GEM. Risk figures are estimates, not official hazard ratings.

Verdict
The clearest difference is price: EarthSafe at Free against iCaelum's $2.99. EarthSafe also leads on in-app purchases (none vs 1) and iOS requirement (15.1 vs 18.0). iCaelum's advantage is update cadence (every 3 days vs every 2 weeks). On ads and device support there is nothing between them.
