Whimsy Weather

Whimsy Weather draws the weather instead of tabulating it. The top half of the screen is a hand-drawn landscape under a real sky. The Sun and the Moon are where they actually are for your latitude and the time of day, the Moon shows its true phase, and the rain, snow, cloud and wind in the picture are the ones in the forecast. The bottom half is the numbers — feels-like, humidity, wind, pressure, visibility, UV, sunrise and sunset, moonrise and moonset. A SKY THAT IS ACTUALLY THE SKY Sunrise, sunset, twilight and the midnight sun are computed, not faked. At 64°N in June the sky never goes fully dark, because it doesn't. Drag the timeline and the Sun and Moon glide along their arcs as the light changes — or tap an hour, or a day in the five-day strip, to jump there. SIXTEEN LANDSCAPES, ALL OF THEM ALIVE Hills, farm, city, beach, harbour, open sea, mountains, desert, lake and the tropics — and every one has something in it that the wind moves. Smoke leans downwind, the windmill turns in proportion to the wind, palms bend and coconuts fall above 60 km/h. People wander through: walking the dog, chasing a hat in a gale. SIX PLACES THAT READ THE WEATHER Taipei 101 shows the cloud base by which floor disappears into it. Fuji puts the freezing level on a cone of known height. The Golden Gate's 1,280 m span is a ruler for visibility. The Eiffel Tower's fountains lean in the wind, and drain in a frost. Liberty stands in water that turns to pack ice. The Pyramids cast the Sun's bearing and altitude across the sand. FESTIVE SCENES On the few days that call for it, the scene hangs lanterns or lights — Chinese, Japanese or Western. The weather itself is untouched. WARNINGS, AND HONESTY ABOUT WHERE THEY CAME FROM Where a national weather service publishes warnings the app reads them and names the issuer — the US National Weather Service, or MeteoAlarm for Europe. Everywhere else it derives its own advisories from the forecast and labels them as derived, rather than dressing them up as official. SEVEN WIDGETS ON THE HOME SCREEN Tonight's sky, with the Moon at its true phase and the planets that are up. Today's conditions. The five-day outlook three ways — icons, floating high and low bars on one scale, and rainfall beside the chance of rain. What to wear. And the scene itself, photographed from the app while it is drawing it. YOURS, IN YOUR UNITS Temperature, wind, pressure and distance each switch independently, or follow your region. English, Français, 繁體中文, 简体中文 and 日本語, system or hand-picked. PRIVATE BY DEFAULT No account. No analytics. No advertising. The forecast comes from Apple's own WeatherKit, and searching for a place goes through Apple's frameworks — so the only thing that leaves your phone is where you want the weather for. FREE AND PRO Free keeps one saved place plus wherever you are, with the full conditions panel, the hourly and five-day forecasts, and warnings and advisories. Pro adds unlimited places, the seven widgets, the other fifteen landscapes, and the timeline to scrub hour by hour — today and the days on either side of it. Subscribe, or buy it once and keep it. NOT A WARNING SERVICE This is a weather app for looking at, not a safety system. For decisions that matter, use your national weather service and follow your civil authorities. SUBSCRIPTION TERMS Whimsy Weather Pro (Monthly) is US$2 per month and Whimsy Weather Pro (Yearly) is US$18 per year; both renew automatically.
