Should you stay or should you go? Know exactly where you stand with the 183-day tax residency rule and the Schengen 90/180 rule. Automatic tracking, custom alerts, and total privacy. Built for digital nomads who take their finances seriously.
Built for serious nomads
183 is precise, private, and works without a subscription. Your location data never leaves your device.
Significant-location monitoring and geo-fencing detect border crossings silently in the background. No tapping. No journaling. Just open the app and your count is right.
A clean, at-a-glance view of days spent per country — current year and rolling 183-day windows. Know your exact standing before you book the next flight.
Different countries use different thresholds. Set 90-day, 120-day, or any custom rule per country, including the Schengen 90/180 rolling window. Long-press a country to edit its rule inline.
iCloud KeyValue sync keeps your data across your iOS devices with Apple's encryption. Snapshot backups let you restore to any prior state — even years back.
