SkyLog is a travel app that brings flight journaling and country stay-day tracking together in one place. FLIGHT JOURNAL • Add flight records manually without a subscription or usage limit. • Look up available flight details by flight number and travel date. • View all flight routes on an interactive 3D globe. • Record flight numbers, airlines, aircraft, airports, times, distance, and duration in one place. • Keep multiple flight legs with the same date and flight number as separate records. FOOTPRINTS, STAY DAYS & SCHENGEN • When enabled and permitted, Footprints can record visited countries and sampled cities automatically. • Review stay days by country and city in list and calendar views. • Import a Google Maps Timeline JSON file to add past country stay days and visited-city records to Footprints. Choose a date range and preview the records before importing. • Set an annual country goal or monitor Schengen days used and remaining under the 90/180-day rule. • Switch between the annual travel goal and Schengen status directly from the Footprints banner. • Home Screen and Lock Screen widgets can show your current country, current journey, D-day from the start of your record, and Schengen days used and remaining. Schengen calculations are reference information based on your recorded stay days. They do not replace official immigration records or legal or visa advice. YOUR TRAVEL STORY • Create a personal travel passport from your flight routes and visited countries. • View statistics for flights, distance, flight time, airports, airlines, aircraft, and visited countries. • Earn achievements and badges. • Revisit years with recorded travel through Year Recap cards. • Back up and restore supported travel data through your SkyLog account and sync it across signed-in devices.

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.
