Window Seat Telemetry

Ever wonder exactly where you’re flying, or what the cabin pressure altitude is at 35,000 feet, but there is no inflight WiFi? Turn your iPhone into a personal offline flight deck with Window Seat Telemetry!

Whether you are a frequent flyer, an aviation nerd, or just a curious passenger, this app brings offline-first flight information right to your window seat. Using your device's built-in GPS and barometer, you get real-time flight telemetry—completely offline, with no expensive airline Wi-Fi required.

Key Features Offline Flight Computer: Enter your origin and destination airports to track your exact flight progress, distance to destination, and estimated time remaining (approximate).

Offline Maps: Watch your plane's real-time position on a detailed map that works with GPS signal only.

Cabin Pressure Analysis: Monitor the aircraft's pressurization in real-time. See the actual cabin altitude and vertical speed (climb/descent rate) using your phone's highly sensitive barometer.

Advanced GPS Telemetry: Get live readouts of your true ground speed, GPS altitude, heading, and GPS vertical rate.

Interactive Charts: Visualize your flight profile with real-time graphs comparing your cabin pressure altitude to your true GPS altitude.

Customizable Units: Easily toggle between Knots, mph, km/h, Feet, Meters, inHg, hPa, and more.

Try It On Your Next Takeoff Download the app and get 5 minutes of free, unrestricted access every single day—perfect for watching the telemetry during the most exciting parts of the flight: takeoff and landing.

Note: This app relies on your device's internal pressure sensor and GPS receiver. A window seat with a clear line of sight to the sky is essential for a GPS lock, hence the name (:
