Tax Residency Tracker: Sarmiza

Sarmiza is the most intuitive way to track your days for tax residency or visa purposes. You select your locations (countries, US States & Territories), set minimum or maximum day limits, and then simply track. It runs completely offline, so your personal data stays on your device. Features include automatic location-based timeline updates, customizable alerts, and an at-a-glance summary of days by jurisdiction for any reporting period.

The app also supports Photo-to-Timeline: generate a travel timeline in seconds offline using location data embedded in your photos. Review and update your timeline anytime, with privacy-first design and on-device data storage. Includes links to the EULA and privacy policy.
