Everything in your pocket

13 algorithms. One phone. Runs entirely offline at 35,000ft.

✈️
Attitude Indicator
Quaternion gyroscope integration with Mahony-style drift correction. Maximum accuracy possible without aircraft-grade equipment — yaw-immune by design.
🌊
Turbulence Meter
G-force RMS classifier calibrated to FAA turbulence severity thresholds. Weight-adjusted per aircraft type — a reading that means the same whether you're on an A380 or an E170.
🏔️
Cabin Altitude
ISA pressure-altitude conversion from your phone's barometer. Tracks the three-phase cabin pressurisation cycle — climb, cruise hold and descent — with auto takeoff/landing detection.
🗺️
Route Tracker
Great-circle route progress with jet stream ETA correction and GPS-off dead reckoning. Divert airport scoring weighted by heading. Keeps working when GPS is unavailable.
📵
Works Offline
Everything runs on-device. No Wi-Fi package, no server connection, no account required. Full aeroplane mode from gate to gate. Your data never leaves your phone.
🎮
In-flight Games
Three offline games built in: Word Bank vocabulary trainer, Times Tables mental arithmetic, and Morse Code with tap trainer and interactive binary tree. Something worth doing on a long-haul. Learn more →

How it works

No special hardware. No internet. Just your phone's built-in sensors.

1
Install the app
Download GeekFlight from Google Play. Works on any Android phone running Android 8.0 or later.
2
Enable sensors
Grant location permission for GPS. The app reads your gyroscope, accelerometer, barometer, compass and GPS automatically.
3
Set your aircraft
Pick your aircraft type from the list. This calibrates the turbulence meter and fills in the Geek Info panel for your flight.
4
Fly with it
Switch to aeroplane mode and open the cockpit screen. All instruments update in real time — no Wi-Fi needed at any point.
Built by a passenger, for passengers

Three years, 40+ releases, and a genuine obsession with getting it right.

GeekFlight started on a long-haul flight with a question: how much is the plane actually banking right now? The answer turned out to be harder to get right than expected.

What began as a gyroscope experiment grew into a full sensor fusion project — quaternion integration, Mahony-style drift correction, ISA pressure models, great-circle routing. Thirteen algorithms running on a phone that most passengers have in their pocket already.

There are no ads, no subscription and no account because there was never a reason to add them. The app is built to be genuinely useful at 35,000ft, in aeroplane mode, with no internet in sight.
