TL;DR — Key Takeaways
- →TripIt and Flighty track itineraries and flight status.
- →They do not apply a 183-day tax test or Schengen 90/180 as a compliance log.
- →Import a calendar or CSV into a residency tracker when you need day totals.
- →A flight app can still be the second source that confirms a trip.
Short answer
Keep TripIt or Flighty for flights. Use a residency tracker when the question is how many days you spent in each country.
What flight apps do not do
- Allocate a trip that crosses a tax-year boundary
- Maintain a rolling Schengen 90/180 total as you add later trips
- Warn you before a tax-residency threshold
- Mark a trip verified because a second source agrees
Export or copy the itinerary into Domicyle Residency Tracker. If the calendar and another import overlap, Proof of Presence can mark that trip Verified. The flight app remains the place you manage the booking.
