Pebbles is a residency, travel, and day tracking application designed for mobile individuals such as expats, digital nomads, and multi homeowners. Its primary function is to help users monitor the number of days spent in different countries and regions, enabling them to stay compliant with tax residency rules, visa requirements, and citizenship obligations. The app organizes travel history by country and rule, providing clear visual breakdowns of progress toward specific thresholds. The application includes a range of features for compliance and planning. Users can track days against the 183 day rule for tax residency, manage multi country and multi state tax compliance, and monitor requirements for programs such as Canada’s 1095 day requirement, EU citizenship paths, and golden visa programs. Pebbles also supports digital nomad visa tracking, visa renewal monitoring, and the Schengen 90/180 day rule. The app offers over 200 ready made trackers and allows users to create custom residency requirements. It provides clear progress indicators and upcoming limit notifications to help users make informed decisions before crossing thresholds. Typical use cases include expats managing tax residency across multiple jurisdictions, travelers ensuring compliance with visa stay limits, and individuals tracking progress toward permanent residency or citizenship. The workflow involves adding a trip in seconds, after which Pebbles automatically organizes each day by country and applicable rule. Users can view their travel history in one place and receive alerts about approaching limits, eliminating the need for manual spreadsheets or calendar calculations. Pebbles is available as a web application at pebbles.day. The platform emphasizes privacy in its residency tracking solution. The interface is designed to be intuitive and clean, allowing users to navigate their data and rules efficiently. Customer support is responsive, with reported quick resolution of technical issues.
