WindXplorer vs Anemogram

Flying a hot air balloon starts with a weather decision. WindXplorer brings together in a single app everything a pilot needs to make it — then to fly, and to keep a record of every flight. BEFORE THE FLIGHT — DECIDE WITH CONFIDENCE View and compare the best weather models (AROME, ICON-D2, UKMO, MET Nordic, GFS) for your launch site, hour by hour and altitude by altitude. The FlyScore distills wind, rain, CAPE, and cloud cover into a 0–100% score: your flying window at a glance, up to 14 days ahead. UNDERSTAND THE AEROLOGY The vertical sounding table and wind rose reveal speed, direction, temperature, and humidity at every altitude. Spot wind shear, pick your steering layers, anticipate your drift. SIMULATE BEFORE YOU INFLATE Plot your predicted trajectory based on your chosen altitude and duration, right on the aeronautical chart with CTR and TMA zones and restricted areas. You know where you're headed before you even lift off. DURING THE FLIGHT — STAY IN CONTROL OF YOUR TRACK Live position on an aeronautical chart, airspace you're crossing, heading, speed, variometer, distance to your planned point. Your chase crew follows you in real time. AFTER THE FLIGHT — KEEP THE RECORD The flight logbook records your flights, photos, and statistics (duration, distance, max altitude). Replay your trajectories, share your best flights, and browse the history of your club or your fleet of pilots. FLY AS A TEAM Save and share your launch sites and favorite places with your crew and your club. Built by and for balloon pilots, WindXplorer is with you from the first weather briefing to the last line of the logbook.

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. Anemogram: from the Greek ánemos, wind, plus -gram, a record. A wind writing.
