Arc vs Anemogram

See rain, temperature and wind together, with a visual forecast you can explore. Arc gives the forecast a shape you can follow. Clouds, temperature and wind move together across one fluid timeline, making the changing day clear at a glance. Hyperlocal forecasts powered by Apple Weather, presented in clear, interactive charts. An atmospheric view brings current conditions to life, with a concise summary of the weather. Explore the days ahead or uncover the details of any hour, right from the chart. Pro adds radar with an interactive timeline, unlimited locations, more frequent updates and weather alerts, plus Home Screen widgets and an Apple Watch experience built around the same visual forecast. Radar coverage varies by region. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Weather as one line you scroll through: what was, what is, what comes. Four styles read the same run of weather, and the app marks the hours worth going out in. FOUR STYLES, ONE SWIPE Swipe up or down and the same run of weather changes language. On first launch the app suggests a style. CLEAR – THE WAY IN For anyone who has never read a meteogram. The temperature line is the horizon. Above it the sky in the light of the hour, on it the weather symbols, below it the sun from sunrise to sunset. Rain falls into its own hour and piles up as a mound on the line: the higher the mound, the more falls; snow is pale. Where it feels warmer or colder than measured, a second edge runs alongside at the true distance. ANEMO – THE WIND The style the app is named after. The white curve is the wind, the pale fringe above it the gusts; the gap between them is what decides a good session from a fight. The ground wears the knot colours every rider reads without thinking: green near 10, yellow 15, orange 20, red 25, violet past 30. Behind it the sky reaches down to the temperature line, in that hour's light: an overcast noon turns grey rather than a dimmed blue. Rain and felt temperature as in Clear. METEO – EVERYTHING The full instrument: wind and gusts on the Beaufort grid, pressure, clouds, humidity, temperature discs and rain bars, every value printed on its own curve. UV rises with the sun, its peak printed bold, and a golden wash is sunshine. On a coast the bottom band fills itself with the tide: high and low water with time and height, plus wave height, period and water temperature. ASTRO – THE NIGHT Stars stand only in hours whose night is genuinely clear; plain black means cloud. The moon stands in the sky the way you actually see it: cirrus lets it through, stratus does not. A real photograph in its true phase, with rise, set and arc. Astronomical darkness stands there to the minute, computed from the sun's altitude rather than the clock. The best night ahead is measured in star hours. Rain as a mound on the line, as in Clear. And red light, for eyes that mean to keep their dark adaptation. Under each date stands only what would change a plan: a meteor shower's peak night, the moon's turning, an aurora chance. Plus the air itself, from crystal-clear to Saharan dust, and the jet stream overhead. There is no seeing figure: nobody can forecast one honestly, so we don't claim it. THE GREEN WINDOW Say what you have in mind and the app finds the hours for it: being outside, wind and water sports, sunbathing, cycling, stargazing. Each profile brings starting numbers, then every one is yours to change: twelve knots is a flat calm to one person and too much for the next. The answer is a green stretch along the chart, in every style. THE WIDGET A daily widget in two sizes: place, temperature, the day as a line, stars in clear night hours, your next window to go outside. Place, period and content are set on the widget itself. THE MAP Your places on a map that becomes a globe as you zoom out. Temperature, wind and rain as layers, with rain radar across Germany. ALSO INSIDE - Places by GPS, search or map, with favourites and history - Units of your choice, applied at once in every style: knots, km/h, m/s, mph or Beaufort, plus temperature, rain and pressure - The past is dimmed, the now line always in sight - Portrait and landscape, iPhone and iPad - Light, dark, or following the sun where you stand - Works offline: the last forecast is there the moment the app opens - English and German FREE, NO CATCH No third-party ads, no in-app purchases, no subscription, no account, no tracking. The developer's own recommendations sit below the chart – switch them off in the settings. Weather data by Open-Meteo (CC BY 4.0), rain radar by Deutscher Wetterdienst.
