Hey Product Hunt! 👋 I'm Roman, an indie iOS developer and digital nomad. I built Borderlog after dealing with visa calculation headaches myself while traveling across Europe and Asia. 🎯 THE PROBLEM If you're a digital nomad or frequent traveler, you know these pains: - Schengen's confusing 90/180-day rule (it's a rolling window, not calendar!) - Accidentally overstaying and risking fines or entry bans - Tax residency (183 days) across multiple countries - Manually tracking visa days in spreadsheets - error-prone and stressful - Searching for visa requirements and application links every time you plan a trip I was constantly stressed about overstaying. Spreadsheets broke. Online calculators gave wrong results. I needed something reliable. ✨ THE SOLUTION Borderlog does the math for you: 📊 Schengen 90/180 Calculator Real-time tracking with precise rolling window calculation. Know exactly how many days you have left, when you must exit, and when you can return. Tested with 24+ unit tests to ensure accuracy. 🏠 Tax Residency Tracker Monitor the 183-day rule per country per year. Stay ahead of potential tax obligations before they surprise you. 🗺️ Global Visa Map Check visa requirements for 180+ countries based on your passport. See at a glance which countries are visa-free, visa-on-arrival, eVisa, or visa required. 📅 Complete Travel History Log every trip with automatic calendar view. Optional location detection or manual entry - you choose. 🔒 Privacy First All data stored privately in YOUR iCloud account. No tracking, no analytics, no third-party sharing. Your travel history is yours alone. 💰 PRICING Free: All core features - Stay tracking & history - Schengen 90/180 calculator - Tax residency tracker (183-day rule) - Basic visa map (visa type for each country) Premium: $9.99/year - Detailed visa information (application links, requirements, processing times) - PDF export of travel history - Priority support for future features 🚀 WHO IT'S FOR ✈️ Digital nomads managing visa restrictions 🌍 Frequent travelers with complex itineraries 💼 Expats monitoring tax residency 🏖️ Anyone dealing with Schengen's 90/180 rule 📱 TECH Built with SwiftUI for iOS 16+. Native, fast, and beautiful. Extensive unit testing for calculation accuracy (because visa mistakes are expensive!). 🙏 FEEDBACK WELCOME This is v1.0 - I'd love to hear what features you'd like next: - Push notifications for visa warnings? - Widgets for home screen? - "What-if" scenarios for planning future trips? - Multiple passport support? Thanks for checking it out! Happy to answer any questions.
