BorderSense: Passport Diary

Visa Tracker and Travel Planner

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 exact same calculation method as the EU's official immigration calculator — so there is no guesswork, no rounding errors, and no nasty surprises at Frankfurt airport.

UK VISITOR TRACKING
Monitor your informal 180-day guideline for UK visits. The rule is unofficial but the consequences are not.

USA, THAILAND, JAPAN AND MORE
Track your 90-day ESTA and VWP allowance for the United States. Monitor Thai tourist and visa-exempt entries. Japan, Australia, Canada, UAE, and the ECOWAS zone are all supported.

CALENDAR VIEW
See exactly how many days you have left on any future date. Plan trips weeks or months ahead. Colour-coded daily view shows your visa status at a glance. Ideal for planning multi-destination itineraries.

MULTIPLE PASSPORT PROFILES
Dual citizen? Managing travel for your family? Create separate passport profiles and track each one independently. Ideal for digital nomads on multiple passports, expats, and frequent business travellers.

PASSPORT CONTROL MODE
At the border and nervous? Switch to a clean, minimal view showing only the essential information an immigration officer needs to see. Professional. Calm. Prepared.

SMART NOTIFICATIONS
BorderSense alerts you when you are approaching your visa limit. Set your own custom warning thresholds. No more frantic day-counting in airport queues.

INTERACTIVE TRAVEL MAP
Visualise your travel history and remaining allowances on a beautiful map. See every country you have visited, understand your exposure across zones, and plan with confidence.

OFFLINE SUPPORT
Everything you need works offline. No internet connection required at the border. No excuses.
