BorderSense
Read full descriptionHide full description
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. WHO IS BORDERSENSE FOR - Digital nomads living the slow-travel life in Europe - Expats and remote workers managing long-term stays - Frequent business travellers crossing multiple visa zones - Backpackers and budget travellers in Southeast Asia and Europe - Dual citizens managing multiple passport profiles - Schengen area visitors from the USA, UK, Australia, and beyond - Anyone who has ever Googled "how many days do I have left in the Schengen zone" WHY BORDERSENSE Other apps approximate. BorderSense calculates. Visa compliance is not a feature — it is the entire product. Built by travellers who got confused by the rules, then built the tool they wished existed. GET STARTED FREE Download BorderSense, add your passport, log your trips, and know exactly where you stand.

The Schengen calculator for the 90/180 rule — days used, days left, and the exact day you need to leave. Flags reads your travel history from your photos, on this iPhone, nothing uploaded, and shows where you stand in seconds. Flags is the simplest, most private way to track your Schengen 90/180 days. Scan your photo library, and Flags builds your travel history from photo metadata. No accounts, no cloud, no sign-ups, no GPS tracking. Your data never leaves your iPhone. WHY FLAGS - 100% private — On-device only. No servers, no analytics, no third parties. - Auto-tracked from photos — Point Flags at your library, and your travel history fills itself in. - No GPS tracking — Ever.

FEATURES - Schengen 90/180 rolling-window calculator - Counts Monaco, San Marino, and Vatican City, the open-border microstates inside the Schengen Area - Over the limit? See the date you're back within 90 days if you leave today - Auto-import from photo library GPS metadata - Manual day entry for phone-less trips or gaps - Visual calendar of every day spent in Schengen - Trip planner: which months are open, whether a trip fits, and the earliest start that works (Pro) - Weekly reminders before you approach the 90-day limit (Pro) - iOS home screen widgets — see your days remaining at a glance (Pro) PLAN BY ASKING On iPhones with Apple Intelligence, the Plan tab becomes a conversation.

EES AND ETIAS READY The EU's Entry/Exit System (EES) is rolling out now: every border crossing is registered digitally, so an inaccurate day count is riskier than ever. Flags keeps your count exact, so there are no surprises at the border. When ETIAS launches, Flags tracks that too — one app, every rule, fully private. FREE TO TRACK, PRO TO PLAN Tracking is free for as long as you like: photo scan, manual entry, today's count, the calendar, and all your history. Pro unlocks the Plan tab, home-screen widgets, and weekly reminders. Choose a yearly auto-renewing subscription or a one-time lifetime purchase. There is no free trial: the free tier is the trial. - Your exact price is shown inside the app before you buy. - Subscriptions renew automatically at the end of each billing period unless auto-renew is turned off at least 24 hours beforehand. - Manage or cancel anytime in your Apple ID settings.
