Your country days.
Confirmed.

It rebuilds your country days from your photos in minutes — you confirm every stay — then watches the line for you: the 183-day rule and per-country and US-state thresholds. It shows a clear verdict (Resident, Not resident, Approaching, Over or Review) before a threshold surprises you; it does not determine tax residence.

It reads the dates already written into your photos to rebuild a travel-day record, then asks you to confirm each stay in two taps — nothing is silently logged. Its App Store listing describes no GPS tracking, account or Flags cloud; you can add or correct missing travel manually.

It watches roughly 239 countries and jurisdictions plus all 50 US states, including thresholds like the 183-day rule and per-country limits. A jurisdiction-specific day count is not a complete residency conclusion; local legislation, ties and treaty positions can matter, so check the current app for coverage.

The UK test is not a simple 183-day rule, and the United States substantial presence test has its own calculation and exceptions. Use Flags as an early warning, then check current HMRC or IRS guidance and obtain advice on a final position.

Yes. A built-in savings simulator lets you see roughly what a different residency split could be worth, so a day decision has a number attached. It is an illustration to explore, not a filing figure — confirm any real position with a qualified adviser.

Yes. Flags is advisor-ready: one tap exports a PDF of your confirmed day counts, drawing on up to five years of history. Keep independent travel documents too, where an adviser or authority needs formal evidence.

A home-screen widget keeps your closest threshold and current day count in view, so a quick weekly check-in is enough to catch a line before you cross it — rather than reconstructing a year from memory afterwards.

Tax residency can depend on more than days. Flags is designed to surface selected ties for review, but it cannot establish the facts or legal outcome that a jurisdiction requires.

Yes — Flags keeps up to five years of confirmed history you can review, and the one-tap PDF export puts it in an advisor-ready form. Keep independent travel documents where an adviser or authority needs formal evidence.

No. Flags is an early-warning tool to stop you tipping over a threshold by accident — not legal or tax advice. Residency rules have exceptions the app deliberately keeps simple. Always confirm your position with a qualified tax professional before you act on it.

The current App Store listing describes an on-device design with no GPS tracking, account or cloud storage. Read the privacy policy for the distinction between your app record and limited, aggregate website measurement.

The app is available through the App Store. Current pricing, trials and availability vary by storefront, so the live listing is the source of truth before purchase.
