Not enough data yet
A guess from speed and the altitude trend. It can be wrong, especially if the phone gives no altitude.
Destination
Pick a destination above to see distance left and an ETA.
Map
Green line: where you have flown. Dashed line: the shortest route between the airports. The arrow is you, pointing the way you are heading. The map is saved with the page, so it works in airplane mode.
Your track
The line appears after the second GPS fix. There is no map, so this works with no network.
North is up. Yellow dot is you now.
What this shows, honestly
- Speed is ground speed from GPS. Airspeed differs by the wind, and the pilot’s instruments show airspeed.
- GPS altitude is not the cockpit pressure altitude. It can differ by hundreds of feet.
- Inside the cabin the signal is weaker. Expect gaps and ±10 to 100 m accuracy. A window seat helps most.
- It does not show other aircraft, your flight number, gates or delays. Those need a data feed that airplane mode cuts off.
- Your track stays in this browser. Nothing is sent anywhere while you track.
How to Use
Open this page on Wi-Fi or mobile data before you board. A line under the checklist confirms it is saved for offline use.
Tap Start tracking once and allow location, then choose your destination airport. Adding this page to the Home Screen is optional.
Turn on airplane mode and make sure Location Services stays on. Wi-Fi onboard is not needed.
Sit at a window if you can. The first GPS fix at altitude can take one to three minutes, and the speed appears once it arrives.
Tap Export GPX after landing if you want the track as a file, or Reset to clear it.

Common Questions
About In-Flight GPS Speed Tracker
Track how fast your flight is moving using only your own phone GPS. The page shows ground speed in km/h, knots and mph, GPS altitude, compass heading, vertical speed, distance flown, maximum speed, and, once you pick a destination airport, the great-circle distance left and an ETA at the current speed. Speed is computed from successive position fixes when the phone does not report it, and poor or impossible fixes are skipped. Open it once on a connection before boarding: it saves itself for offline use with a service worker limited to this page, needs no map tiles, and keeps working in airplane mode while Location Services is on. It shows ground speed, not airspeed, and no flight numbers or other aircraft. The track is kept in your browser and can be exported as GPX.
Processing Note
In-Flight GPS Speed Tracker runs in your browser, so the input you enter is processed locally on this page and is not uploaded to a ToolMintX account.
Tool Limits
These tools do plain arithmetic on the times you enter and the rules we last checked. They do not know live delays, gate changes or queue lengths. Always follow the airline and the airport screens.
