Residency - Day Tracker

Your phone quietly counts the days you spend in every country — and warns you before you cross the 183-day tax-residency line. Your location never leaves your device.

Cross borders freely. Never lose count.

If you split your life between countries, one number rules everything: how many days you've spent where. Cross the 183-day line without noticing and the cost can be life-changing. Residency counts your days automatically, so you always know where you stand.

PASSIVE BY DESIGN Enable tracking once. Your iPhone detects country changes in the background — no check-ins, no spreadsheets, no boarding-pass archaeology. Open the app to a live count for every country in your year.

WARNED BEFORE IT MATTERS Tiered alerts at 30, 14, and 7 days of headroom, and the moment a projected crossing approaches. The warning arrives while you can still change your plans, not after.

PRIVATE TO THE CORE Your precise location never leaves your phone. Country detection runs entirely on-device against offline maps — no geocoding services, no location servers, no trackers, no ads. Optionally sync only country-level day totals to back them up.

HONEST NUMBERS Conservative any-presence counting (a travel day counts in both countries). Tracking gaps are never hidden — assumed days are flagged for your review, and every manual correction is kept in an audit trail you can stand behind.

BUILT FOR Founders, investors, and internationally mobile families managing the 183-day rule, snowbirds, non-doms relocating, and anyone whose accountant asks "how many days were you there?" every spring.

Residency is a record-keeping tool, not tax advice. Review your counts with your advisor.
