iPhone
How many days have you spent in each country this year? Your photos already know. Country Days Tracker rebuilds your travel history in about a minute — read on your phone, never uploaded — and you confirm every trip in two taps. No GPS. No account. No tracking.
Then it keeps watch: the 183-day rule and per-country thresholds, counted the way each tax authority counts them, with a clear safe / close / over answer — and a warning before you cross any line.
Already splitting your year between countries? See what your travel pattern could save you in tax — based on the days you actually spend, not a fantasy relocation.
ONE STATUS, ONE GLANCE
• Every jurisdiction you watch, ranked by risk
• Clear verdicts: Resident · Not resident · Approaching · Over · Review
• Your primary residence anchored at the top, regimes (like NHR) and all
YOUR DAYS, WITHOUT BEING TRACKED
• Reads the date and coarse region your photos already store — using offline maps, on device
• No location permission, ever. No background tracking.
• Missing a stay? The app spots the gap and suggests where you were — you confirm, or add it by hand
IT'S NOT ONLY HOW LONG YOU STAY
• Flag where your home, family, or work is — for most countries any of those can make you resident regardless of days
• The UK's Statutory Residence Test uses those ties to lower your day limit (simplified)
• US citizens are reminded that citizenship-based taxation follows them anywhere
NOTHING SLIPS BY
• Spending too long somewhere you don't track? Flags suggests it — and starts watching automatically once you're near the line
• Step back through this year and the last five: final status for every place that mattered, plus the exact dates of each stay
SEE WHAT YOU'D SAVE
• Estimated tax across the places you actually spend your year — ranked cheapest-first
• Anchored to your real days, not a fantasy relocation
• Indicative rates for planning conversations — not advice
FOR YOUR ACCOUNTANT
• A one-tap, advisor-ready PDF day-count report for any jurisdiction
• Every day sourced: photo-confirmed or entered by you
BUILT FOR HOW RESIDENCY ACTUALLY WORKS
• All ~239 countries plus the 50 US states and DC
• Each jurisdiction keeps its own tax year — the UK's 6 April, India's 1 April, Australia's 1 July, calendar year by default
• Plain-English rule text for major destinations
• Home-screen widget and an optional, quiet weekly check-in
PRIVATE BY CONSTRUCTION
Residency and the days you spent abroad are sensitive. So we built the app that can't see them: no account, no sync, no analytics SDK, no ad network. Everything runs on your iPhone, offline. Delete the app and it's gone.

Country Days Tracker: Flags is an early-warning tool to stop you tipping over a threshold by accident. It is not tax, legal, or financial advice, and it deliberately keeps complex rules simple. Always confirm your position with a qualified tax professional before acting on it.
