Devil's Chariot
Travel
Free · Designed for iPad. Not verified for macOS.
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.

FLIGHT REPLAY
Watch your logbook play back on the globe, one flight per second, in the order
you flew them. Play, pause, and scrub from the dashboard.
AIRLINE STATUS AND UPGRADE RATE
Record your elite status history in Settings — American, Delta, United, Alaska
and more, with the date each tier started. The dashboard then shows how often
status put you in a premium cabin, next to the Cabin Class chart. Tap a flight
to say the seat was bought or cleared with a certificate, or name the cabin you
ended up in, and every chart follows.
MAP
State and province borders now draw from high-detail data for the United
States, Canada, Mexico, Australia, China and Russia, and fade in as you zoom.
Tapping a route highlights it.
ALSO
• The dashboard shows when the logbook was last imported.
• Re-importing a logbook keeps your cabin corrections.
• The upgrade rate counts only flights you have taken, never ones you have
merely booked.
• Blank cabin cells in a Flighty export count as Economy, matching every other
chart.
• Flight times no longer print as "2h 60m".
• The flight log says why it is empty when a dashboard filter hides everything,
and how to clear it.
• The replay scrubber works with VoiceOver.
• The launch screen matches the app icon.
• "This device" replaces "this iPhone" throughout, since the app runs on iPad.
• Interrupted database upgrades can no longer leave the logbook unreadable.
• Delete All Flights clears every trace, including cabin corrections.
