Weather for hot air balloon pilots: multi-model forecasts, windgram, trajectory simulation, live flight tracking and logbook. Built by pilots, for pilots.
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.
Ratings & Reviews
This app hasn’t received enough ratings or reviews to display an overview.
NEW
• Windgram: wind & cloud time × altitude cross-section in its own tab, with weather model selection
• Live wind stations on the Radar, Track and Simu maps: OpenWindMap, Météo-France and METAR, with freshness and direction at a glance
• Simulation: custom flight profile — draw your climb, levels and descent, with presets
• Offline maps: download named areas and keep your basemaps in flight, even without network
• Airfields on the map with TWR/AFIS/ATIS frequencies (ICAO layer)
• Thermal activity: local convective layer estimate, factored into the FlyScore
• Vertical image export for the windgram and the simulation
IMPROVED
• Reworked wind engine: unified altitude grid, precise AMSL reference, consistent trajectories everywhere
• Wind table: frozen Takeoff row, dynamic Ground row, AGL marker, crossed layers greyed out
• More reliable takeoff detection (15/50 m above ground)
• Places map: redesigned search and filters on mobile
• Faster loading of forecasts and airspaces
FIXED
• Stronger iOS stability (memory, maps, long sessions)
• Display adjustments on iPhone (safe areas, toolbars)
