4Cast Weather

4Cast is a weather app for people who want more than a temperature: Apple Weather's forecasts, minute-by-minute rain, a live radar and a sky that reflects the one outside. One purchase. No subscriptions, no ads, no tracking. ASK 4CAST Ask about the weather in your own words, in the Ask tab or with Siri: will it rain this afternoon, what to wear, the best time for a run. Answered on your iPhone, with Apple Intelligence where it is available. SKY MOMENTS How colourful the sunset should be, when a rainbow may show, when the night is clear for stars or the aurora. Tonight's sky: the Moon, the planets, meteor showers and eclipses, with the clouds. Each can notify you. Share any of your skies as a picture or a six-second loop. YOUR DAY Your plans with their weather: each event with a place gets the forecast for its place and hour, a note the evening before when it matters and, for a plan away from you, when to leave. The best hours for a run, a ride or the stars, within your own limits. Your calendar is read on your iPhone and never changed. ON THE ROAD The weather along a drive at the hour you pass each stretch, on a map and in words, and whether leaving later is drier. STORM WATCH Hurricanes, typhoons and tropical storms with their track, cone and winds, and when their winds should reach each of your places. NOAA's outlooks of severe storms and flooding rain, days ahead. Lightning over the Americas live on the map.
