Links

Links is an iOS app for tracking days spent in each country for tax residency and travel reporting. It checks in a few times a day, turns each fix into a country and deletes the coordinates, then builds those check-ins into stays you can correct by hand. Limits like Schengen 90/180 and a country's residency threshold are counted live, each the way that rule counts. Stays sync across signed-in devices and export as CSV. No analytics, no advertising, no third-party trackers.
