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
• Thermal activity: local convective layer estimate, new dedicated chip, factored into the FlyScore
• Offline maps: download named areas and keep your basemaps in flight, even without network
• Crew on the road: chase vehicles on the map, one-tap navigation via Waze / Google Maps / Apple Maps, push notifications for the crew
• Bluetooth temperature probe (Ruuvi / HotAir) in beta
• Vertical image export for the windgram and the simulation
IMPROVED
• Fully reworked wind engine: unified altitude grid, precise AMSL reference, consistent trajectories across simulation, planner and map
• Wind table: frozen Takeoff row, dynamic Ground row, AGL marker, already-crossed layers greyed out, auto refresh
• Full translation of the app into English, Spanish and German
• Refreshed interface: simpler navigation, unified Logbook, optimized tablet layout
• Logbook: comment replies, faster feed, reading position remembered
• Places map: redesigned search and filters on mobile
• Competition tools: Task Solver, Cone Navigator, Best Left/Right, 2D/3D replay
FIXED
• Stronger iOS stability (memory, maps, long sessions)
• GPS: reliable distance, altitude and vario, including after returning from background
