What Inkpass does

Inkpass is a digital companion for the Passport To Your National Parks hobby — the one place where every cancellation stamp you've ever collected is cataloged, photographed and safe. Your physical passport book is irreplaceable: there is no central archive of cancellation stamps, books get lost at stamping stations, pages run out, and impressions smudge. Inkpass is the backup the blue book never had. It covers the whole system, not just the famous 63. Browse all 433 National Park Service units — parks, monuments, battlefields, seashores, historic sites — grouped into the nine official passport regions, exactly the way your book is organized. Mark a unit visited, then log each individual cancellation: which visitor center or stamping station it came from, the date on the dater, the ink color, and whether it was a bonus or special-event stamp. Many parks have a half-dozen stations; Inkpass tracks them stamp by stamp, so you always know which ones you're still missing before you drive away. Progress is half the fun. Region rings and a state-by-state map show how much of each passport region you've completed, and a trip journal ties stamps, parks and notes together so every outing becomes a story you can scroll back through years later. Inkpass works with no signal at the bottom of a canyon. It is 100% offline, has no account and no sign-up, and stores everything in SwiftData right on your device — your travel history never leaves your phone. • All 433 NPS units, organized by the nine official passport regions • Per-station cancellation log: location, date, ink color, bonus stamps • Photo capture of every impression — a real backup of your book • Region progress rings and state-by-state coverage • Trip journal linking parks, stamps and notes • Fully offline, no account, nothing synced or shared If your passport book is the collection, Inkpass is the catalog.
