# DaysAbroad > DaysAbroad is an iOS app that automatically tracks how many days you spend in each country using GPS.

Arrival and departure days both count. The window is not calendar-anchored. - **Tax residency 183-day rule**: most countries treat a person as tax-resident if they spend 183+ days in the country during a calendar year. Many countries have additional second-tier tests (ties, home, family, economic interests). - **US Substantial Presence Test**: weighted formula across the current year and prior two years (count current year fully, prior year × 1/3, year before × 1/6). - **UK Statutory Residence Test**: a multi-pronged test that can establish residence with as few as 16 days for someone with sufficient UK ties. ## Key pages - /llms-full.txt — Expanded summaries of every guide for LLM ingestion - /guides — All guides hub - /guides/travel/ — Travel track (tourist visas, day-counting basics) - /guides/tax-residency/ — Tax-residency track (183-day rule, country guides) - /guides/visas/ — Visa track (Schengen, digital nomad visas) - /tools/schengen-calculator — Free Schengen 90/180 calculator - /use-cases — Use-case hub - /use-cases/digital-nomads — DaysAbroad for digital nomads - /use-cases/business-travelers — DaysAbroad for business travelers - /pricing — Pricing tiers - /features — Full feature list - /about — About DaysAbroad ## Editorial stance - Always informational, never legal/tax/immigration advice. - Every fact links to a primary government source where available. - "Last reviewed" dates on every guide. - Plain language; declarative answers near the top of each page. ## Sitemap https://daysabroad.app/sitemap-index.xml ## Contact support@zebralabs.org
