Trackora - Automatic country-day tracking for visas & tax residency

Trackora automatically counts how many days you spend in every country — Schengen 90/180, 183-day tax rules, visa limits, residency absence rules. It rebuilds years of past travel from photo metadata and boarding-pass barcodes, warns you before you hit a limit, and exports audit-ready PDF reports. Everything runs on-device: no account, no servers, your location history never leaves your phone.
