- People tracking tax residence or visa days across countries
- Worth noticing
- The page says counters cover 40 countries' rules and cite the sources behind each rule.
Field notes
The described workflow combines daily location notes with evidence found in photos, Wallet boarding passes, PDFs, screenshots, and card statements. The page says users could review unsupported days and export a yearly PDF; it also says the app would have no account or analytics and would keep travel history on the device. These are product claims on a pre-release page, not verified app behavior.
