The Passport is your travel history made real: every country and city you have been, organized by year, built automatically from your timeline.
What counts
Spend time somewhere and it counts. Cities collect the days you spent in them, countries collect their cities, and each year gets its own page, so you can flip back through your life the way you would flip through passport stamps.
The lifetime odometer
Your passport also adds up every mile you have ever traveled while tracked, across every mode, from daily walks to long-haul flights.
Growing it
There is nothing to maintain. Keep tracking, keep traveling, and the passport fills itself in. Past trips appear too when you import your history.
