Name the motion
A seat turbulence index, peak g and RMS values help separate a sensation from a measurable event.
Flight data for calmer passengers
SteadySky
Track your flight offline, see real GPS data, and compare turbulence forecasts with what your phone actually measures in the cabin.
For nervous flyers, clear numbers can make the unknown smaller: speed, altitude, route, ETA and turbulence become understandable instead of invisible.

GPS tracking path
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.
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.
Complete Android launch scope
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.
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 estimate, satellites, point quality and every key flight value.
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.
What it measures
Real flight data, translated for passengers.
The app turns raw sensors and public aviation weather into readable values that help you understand the flight from your seat.

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.
