Residency tracker: Residex.io

Residex counts the days you spend in each country, and warns you before they add up to a problem.

Cross 183 days in the wrong place and you may become tax resident there. Spend 90 days in the Schengen area and your allowance is gone. These lines are easy to cross without noticing. Residex is the app that notices for you.

PROOF FROM YOUR PHOTOS
Your photo library already records where you have been. Residex reads the date and place saved in your photos — on your device, nothing uploaded — and keeps those days as proof of where you were. It is the fastest way to rebuild years of travel you never wrote down.

EVERY COUNTRY COUNTS DIFFERENTLY
Most trackers count to 183 and stop. Residex app actual rule:
• Schengen 90/180 across all 29 member countries exit days the way the rule does
• The US substantial presence test — this year's last year's, plus a sixth of the year before
• The UK's 6 April tax year, counted in midnight
• Thailand's 180 days, Portugal's rolling twelve months, and more
• 19 presence rules across 70 countries

KNOW BEFORE YOU CROSS
• Get notified on the date a trip you have already planned would take you over a threshold
• Warnings as your days approach a limit, not after
• Long absences that may put a US green card, UK, Canadian permanent residence at risk
