Visa and tax-residency day tracker
iOS app for tax residency and visa day tracking. Counts days per country against Schengen 90/180, UAE 183-day, UK SRT, and US SPT rules, with visa reminders and a travel timeline.
the problem
Digital nomads, expats, and frequent travelers have to track days spent in each country to stay within visa limits and tax-residency rules, and most people do it in spreadsheets or not at all.
→ the approach
- Kept the app local-first: trips and documents stay on the device, protected by Face ID, with user-controlled backups.
- Modeled residency rules as data, including Schengen 90/180, UAE 183-day, UK Statutory Residence Test, and US Substantial Presence Test.
- Reconstructed past trips from photos and optional GPS so users do not have to type in years of travel.
- Shipped with Expo and an automated EAS pipeline that builds and submits to the App Store.
