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, ranked by how many airports in each • 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.

Read full description

Seat 12A is a personal flight log. Add the flights you have taken and watch them draw themselves across a 3D globe you can spin, tilt and zoom. It is yours, and it stays yours. Your flight history is free and unlimited — every flight you log, for as long as you keep the app, with no account to create. No advertising. No analytics. Your flights live on your device and, if you want them on more than one, in your own private iCloud — an area of your Apple account that not even the developer can read. ADD A FLIGHT IN SECONDS - Scan a boarding pass — the barcode is read on your device - Import flight reservations already sitting in your calendar - Or just type it: search over 6,000 airports offline A GLOBE, NOT A LIST - Every route drawn as an arc between real airports - Watch a single flight fly its own path, start to finish - Five hand-built globe styles: Night, Daylight, Satellite, Midnight, Ember - Countries you have visited, lit up WHAT IT ADDS UP TO - Distance flown, hours airborne, countries and airports visited - A passport that fills with country stamps as you travel - Achievements worth actually earning — including the distance to the Moon - Your busiest routes, favourite airlines and year-by-year history WORKS ANYWHERE The airport database, the airline marks and the globe itself are all built into the app. It works at 30,000 feet with the Wi-Fi off. PRIVATE BY CONSTRUCTION There is no server to send your data to, because there isn't one. The camera is used only to scan a boarding pass, on your device. Your calendar is read only on your device, only to find flights. Neither leaves your phone. No paywall around your own history. Not now, not later.
