Everything you need.
Nothing you don't.

183 is precise, private, and works without a subscription. Your location data never leaves your device.

📍

Automatic Tracking

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.

Days Gone Dashboard

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.

⚙️

Custom Rules & Schengen 90/180

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.
