Scan your boarding pass, tap Start, and your iPhone's own sensors record the flight from takeoff to landing. Your flight record is not copied from third-party flight data. It holds only what your GPS, barometer and motion sensors actually measured. It is a record that you were there. ■ Recording · Scan the boarding pass barcode to fill in flight number, route and seat · Or share a booking confirmation email to add the boarding pass · One sample per second, takeoff to landing · Altitude, ground speed, G-force, cabin pressure altitude · Automatic phases: taxi, takeoff, cruise, landing, taxi · Keeps recording with the screen off or another app open ■ Before you fly, after you arrive · Home shows your next flight with its route map and a to-the-second countdown · Flight briefing: your aircraft, gate, and weather at the destination · Arrival guide: baggage belt, arrival gate, immigration hall, and where to catch your rideshare (some details aren't available at every airport) ■ After you land · Measured takeoff and touchdown times, and time airborne · Peak altitude, speed and G-force · Your actual GPS track on a map · Takeoff and landing runway identification · Arrival airport stats and carbon footprint ■ Logbook · Your flights add up into a personal aviation logbook · Keeps the aircraft you flew (type, registration, photo), seat and gate · Search by flight number or route · Import past flights from another app's CSV, and export all your flights as CSV ■ Records: collections and habits · Airlines and alliances, airports and runways, countries, and every aircraft you've flown become collections · Aircraft details: photo, specs, registration history, and your flights on it · Cabin pressure profile and personal records · Your seat habits, on-time rate, and a year in review that opens each December ■ Your data stays yours · Raw GPS coordinates stay on this device and in your own iCloud. They are never sent to our server · Only your boarding passes and flight summaries (flight number, times, peak values) are backed up · Email import sends only the text of the email you share, to read the flight details · Delete everything, or your whole account, at any time ■ About GPS in the cabin Reception depends heavily on where you sit. In our own measurements, window seats recorded 95-100% of the flight while non-window seats managed 14-53%. Sitting by a window and keeping your phone near it makes a large difference. A gap in the GPS track is not a failed recording. Altitude, G-force and flight phases keep recording from the barometer and motion sensors. ■ BUSINESS · Offline route maps so you can follow the route with no internet in the air · A full PDF of each flight record, and watermark-free share cards · See where the aircraft you flew is flying today · An aircraft's full registration history, and on-time rates by airline · A single-flight pass is available if you would rather not subscribe Available in English, Korean and Japanese.

About

Devil's Chariot

Features
Read full description

Devil's Chariot analyzes a Flighty CSV export. It imports your flight history and breaks it down into rankings, charts and maps, on the device, with no account and no network connection. The focus is on derived statistics rather than the log itself: itineraries reconstructed from connecting legs, alliance share over time, hub and terminal rankings, aircraft body types, cabin class including budget carriers, red-eyes, and travel pacing. SEGMENTS AND ITINERARIES Both are counted. A segment is one operated leg. An itinerary is a complete journey from origin to final destination, reconstructed by joining legs across layovers of up to eight hours. SFO to DEN to LGA is two segments and one itinerary. Segments and itineraries are ranked separately, and direct and connecting itineraries are listed on their own as well. FLIGHTS OR MILES Every ranked panel switches between the two. Airlines, aircraft, routes, cabin classes and alliances can each be sorted by how often you flew them or by how far. BREAKDOWNS • Alliances: Star Alliance, SkyTeam, Oneworld and unaligned carriers, with each alliance's share plotted year over year • Connection hubs, ranked by layovers rather than departures • Terminals, ranked by visits • Aircraft by body type: wide-body, narrow-body and regional, each expanding to the individual models • Cabin class, counting budget-economy carriers separately from full-service economy • Red-eyes, ranked as their own route list • US states you have landed in, drawn as a map • Year-to-date pacing, compared against previous years • Flight frenzy: the rolling window in which you flew the most • Flights by year, and cumulative totals over time MAP Routes draw on a rotating globe. Drag to spin, pinch to zoom. Upcoming flights render in green alongside flights already taken. FILTERS Switch between Past, Upcoming and All, or select a single year. Every panel and the globe re-scope together, so all figures describe the same set of flights. OFFLINE AND PRIVATE The app makes no network connections. There is no account, no sign-up and no analytics. The airport dictionary, map geometry and all calculations are bundled in the app, so every screen works without a connection. Flight data is stored on the device only. Deleting the flights in Settings, or deleting the app, removes it entirely. IMPORTING Export a CSV from Flighty: Settings → Account Data → Export your Flights. Flighty emails you the file; save it to Files and import it in the app. Any CSV with the same column headers will import. Try with Sample Data loads a complete example logbook if you want to see the app before importing your own. Devil's Chariot is an independent app. It is not affiliated with, endorsed by, or connected to Flighty.
