TL;DR — Key Takeaways
- →The 183-day rule is a presence count per country in a tax year. It is not a flight history.
- →TripIt and Flighty organise itineraries. They do not total tax days or flag a threshold.
- →Nomad List is for choosing cities. It is not a log of where you already were.
- →A residency log that stores the year, imports a calendar, and marks corroborated trips is the tool built for the count.
Short answer
The useful 183-day tool is the one that stores a full year of nights per country and tells you when you are close to a threshold. Flight apps and city directories answer different questions.
What each kind of tool is for
| Tool | Built for | Not built for |
|---|---|---|
| Spreadsheet | A short year you update yourself | Rolling windows, alerts, and a second source of proof |
| TripIt or Flighty | Flights, alerts, and itinerary | Tax-year day totals and 183-day warnings |
| Nomad List | City cost, weather, and community | A personal record of days already spent |
| Domicyle Residency Tracker | Per-country day counts, Schengen 90/180, imports, and a what-if check | Filing a tax return |
Domicyle Premium Residency Tracker keeps the year. Proof of Presence marks a trip Verified when two sources agree. Free use of the tracker is capped; the public Schengen check is a one-off tool, not the year log.
