METEO & SPAZIO doesn't just show you a tiny cloud icon: it paints the exact sky you see out your window. The background is generated live from real-time measurements—daylight aligns with the time and season of your location, clouds gather as they actually do, rain falls with the intensity derived from data, and the sea ripples to current wave heights. On the horizon, your city's skyline appears alongside its iconic landmarks. FORECASTS Current conditions, hourly 24-hour predictions, and a 10-day forecast featuring feels-like temperature, wind speed, gusts, humidity, pressure, UV index, sunrise, and sunset. Sea state and wave heights for coastal areas. Air quality index based on the European standard, complete with PM2.5, PM10, nitrogen dioxide, and ozone levels. Severe weather alerts directly on the location tab, plus nearby earthquake warnings with magnitude and distance. Data is powered by Open-Meteo and remains readable offline. LIVE ETNA In eastern Sicily, the volcano shapes the landscape, and the app treats it accordingly: the background plume mirrors the real one. The dedicated monitoring tab displays the aviation color code, the official INGV VONA bulletin translated side-by-side with the original text, estimated ash plume dispersion based on high-altitude winds, and live status for Catania Airport. 3D CRATER VIEW The crater view is built using high-precision elevation data overlaid with real orthophotos: orbit around the mountain, unlock the camera, and explore the 3D model all the way down to the coast. The sky above is rendered for the crater's exact coordinates, showing the Sun, Moon, planets, and constellations precisely where they are right now. Live telemetry brings you INGV visible and thermal camera feeds alongside peak microclimate data at 3,300 meters. AVIATION Official METAR and TAF reports via NOAA for airports worldwide, decoded into plain language as well as raw text. Flight categories, wind, visibility, QNH, cloud cover, and the wind-preferred runway. Toggle aviation mode to turn the main screen into your chosen airfield. MAPS & RADAR Animated precipitation radar and satellite cloud cover with an interactive timeline. Long-press anywhere on the map to inspect weather, coordinates, and altitude, then save the location if you choose. SKY & SPACE An interactive Solar System powered by NASA/JPL Horizons ephemerides: planets, moons, the ISS, asteroids, and comets positioned in real time, complete with atmospheric and orbital data sheets. Zoom out beyond the solar system to explore exoplanets and known black holes. The immersive sky view turns your phone into a window to the cosmos: move your device and constellations shift in real time. Also includes eclipses, moon phases, space weather, and Voyager probes tracking distance in light-hours. ON YOUR PHONE Home screen widgets styled with colors dynamically extracted from your background. Live weather wallpapers, app icon shortcuts, and a standalone WatchOS app. Ask Siri for weather updates—even when your screen is off. Secure backup stored in a private iCloud folder, accessible exclusively by this app. TWO INTERFACES Switch seamlessly between two distinct design styles: a translucent glass look revealing the sky behind panels, or Material Design matching your system theme. Features immersive ambient audio matching current weather conditions, finely tuned haptic feedback and voice reading COMPATIBLE WITH APPLE WATCH AND IPAD SOURCES Open-Meteo for forecasts and air quality; INGV – Osservatorio Etneo for volcanic activity; NOAA for aviation data; NASA/JPL Horizons for ephemerides; RainViewer and EUMETSAT for radar and satellite imagery; MapTiler for map rendering. Also fully credited within the app. The app is free and supported by ads. A one-time purchase removes advertisements, unlocks unlimited saved locations and airports, and enables the glass theme. I have poured my heart into this project and hope you enjoy the app! Wishing you clear skies!
