BorderSense: Passport Diary

⚠️ DISCLAIMER: BorderSense is an independent app and is not affiliated with, endorsed by, or representative of any government entity or immigration authority.

Know your visa limits before a border officer does. BorderSense is the precision travel companion for digital nomads, expats, frequent flyers, and dual citizens who need to stay on the right side of immigration law — without a law degree.

Getting your visa days wrong is not a minor inconvenience. It means fines, deportation, future travel bans, and a very awkward conversation at passport control. Spreadsheets fail. Mental math fails. Generic travel apps fail. BorderSense does not.

WHAT BORDERSENSE DOES
BorderSense tracks your visa allowances across multiple countries and zones, calculates remaining days with precision, and alerts you before you accidentally overstay.

SCHENGEN CALCULATOR
The Schengen 90/180 rolling day rule is the most misunderstood visa rule in the world. BorderSense uses the same calculation methodology as the EU's Short-Stay Visa Calculator. Always verify your status using the official EU tool: https://short-stay-schengen.ec.europa.eu

UK VISITOR TRACKING
Monitor your informal 180-day guideline for UK visits. For official UK visa and entry guidance, visit: https://www.gov.uk/check-uk-visa

USA, THAILAND, JAPAN AND MORE
Track your 90-day ESTA and Visa Waiver Program allowance for the United States. Official ESTA information: https://esta.cbp.dhs.gov
For Thai visa information: https://www.thaiembassy.com or https://www.immigration.go.th
