Check flight turbulence before takeoff
Use an internet connection before the flight to consult or download the turbulence forecast available for your route.
Turbulence before takeoff. Flight data in the cabin.
SteadySky Turbulence Tracker
Check route turbulence before takeoff. In the cabin, follow GPS position, altitude, speed and route offline, with a local seat-level movement estimate from your phone sensors.
Forecasts and sensor estimates are informational and recreational. SteadySky never replaces the crew, official instruments or flight-safety information.

Before and during your flight
Plan with a forecast. Keep tracking offline.
SteadySky brings turbulence forecasts, offline flight tracking and real in-flight measurements into one clear passenger view.
Follow altitude, speed and route
During the flight, GPS flight tracking and offline maps can monitor altitude, speed and route according to the app, device and available GPS signal.
Understand indicative cabin movement
Real in-flight turbulence measurement uses phone sensors and depends on the device and its placement. SteadySky can support nervous flyers, but never replaces crew, airline or aeronautical information.
Your numbers, your way
One flight. Three unit systems.
Choose a system during setup and change it later in Settings. Your choice follows you across the app.
Metric
Kilometres, metres and Celsius for a familiar everyday view.
Aviation
Knots, feet and nautical miles for a cockpit-style reading.
Imperial
Miles per hour, feet, miles and Fahrenheit throughout the app.
For fear of flying
Less mystery in the sky.
Turbulence is often frightening because passengers cannot see what is happening. SteadySky turns the flight into readable context: where you are, how fast you are moving, how high you are, what the route looks like, and how cabin movement compares with the forecast.
Name the motion
A seat turbulence index, peak g and RMS values help separate a sensation from a measurable event.
See the route
Maps, ETA and arrival distance replace "how much longer?" with a visible path forward.
Keep control simple
The core tracker works in airplane mode with local GPS, so the calm data is available when the cabin is offline.
Before, during and after the flight
Built like a passenger cockpit.
SteadySky combines offline tracking, route intelligence and turbulence awareness in one Android app.
Offline GPS tracking
Track speed, altitude, heading, distance, climb and descent with the phone GNSS sensor, even in airplane mode.
Flight Display — Live
A glass-cockpit instrument driven by your GPS: attitude, speed and altitude tapes, vertical speed and heading, with optional aviation units (kt, ft, NM).
Turbulence forecast
Check route turbulence from upper-air weather, Open-Meteo, OpenSky anonymous tracks, NOAA AWC PIREP and SIGMET data.
Measured cabin motion
Use the accelerometer for a seat-level turbulence estimate with index, peak g and RMS values.
Offline map and radar
A world base map is included. MapLibre, PMTiles/MBTiles support and radar fallback keep the route visible.
Airport route search
Search more than 4,000 airports by city, name or IATA code, then follow ETA and arrival distance.
Live dashboard
View AGL on approach, outside air temperature calibrated with real ground weather, satellites, point quality and every key flight value.
Screen-off tracking
A foreground service keeps tracking active in the background, with a rich notification showing your live flight status.
History and exports
Save sessions locally, review the track, and export flight data as GPX, CSV or JSON.
Private by design
No account, no analytics, no developer server. GPS sessions stay on the device.
New in the app
A glass cockpit in your pocket.
The Flight Display turns your phone into a passenger PFD: an attitude indicator, speed and altitude tapes, vertical speed and heading — all driven live by the phone's GPS, fully offline.
- Attitude, speed, altitude, vertical speed and heading in one instrument.
- Optional aviation units: knots, feet and nautical miles, like a real PFD.
- The screen stays on while the display is open — built to be watched.

Privacy and data sources
Your GPS track stays with you.
SteadySky has no developer server for your flight sessions. The offline tracker processes GPS locally; the optional turbulence section uses public sources only when you request online data.

Good to know
Questions before boarding.
Can SteadySky be used for flight safety decisions?
No. SteadySky is informational and recreational. It must not be used for aeronautical navigation, flight safety or operational decisions.
Does offline GPS work in airplane mode?
Yes, if the phone keeps system location enabled. GPS fix can take a few minutes in the cabin and usually works best near a window.
Does the turbulence section need internet?
Yes. Forecast, PIREP, SIGMET and weather data come from public online services. The core GPS tracker remains offline.
Which languages are planned?
English, Italian, French, German, Spanish, Russian and Chinese are planned for the Android interface.
What is the Flight Display?
A passenger-style primary flight display (PFD) rendered from your phone's GPS: attitude, speed and altitude tapes, vertical speed and heading. It works fully offline, can switch to aviation units (kt, ft, NM) and is a Pro feature, currently marked experimental.
Can I change units across the whole app?
Yes. Choose Metric, Aviation or Imperial during setup and change it later in Settings. The selected system applies across SteadySky.
