Stampr Passport
Your National Parks. Stamped.
Free · Designed for iPad. Not verified for macOS.
Your National Parks. Stamped. Stampr is the only iOS app that combines: (1) bundled offline 63-park dataset, (2) animated stamping moment with haptic, (3) automatic.
Stampr is the digital passport for the 63 US National Parks — and the 325M visitors who pass through them each year.
Log a visit in three taps. Watch a beautifully-rendered stamp press into your passport with a satisfying haptic. Watch your progress against the "All 63 National Parks" challenge climb. See your years of trips laid out on a map, on a calendar, on a printable passport book.
Stampr is built like a keepsake, not a checklist:
— Tap-to-stamp: log a visit in under 30 seconds with date, photos, and optional notes. A grayscale outline transforms into a full-color cancellation stamp with a deeply satisfying animation.
— All 63 National Parks: bundled offline. No network needed to browse, read, or log.
— Auto-detected visits: iOS's CLVisit framework spots when you've actually been at a park. Get a gentle "Did you visit Yellowstone?" prompt afterwards. Always opt-in.
— Map of the country: visited parks render in color; unvisited stay grayscale; want-to-visit get a heart pin.
— Stats dashboard: progress ring, calendar heatmap, states-visited map, longest streak, region badges.
— PDF export: print your full passport as a coffee-table book. One page per park with stamp, photos, and notes.
— Privacy by default: no account, no email, no analytics SDK, no third-party tracker, no server. Photos are referenced from Apple Photos by identifier — never duplicated.
— Free, forever: every feature is included. No subscription, no ads, no IAPs.
Stampr is for the family on a road trip, the retiree checking off Acadia, the pursuer running all 63, the parent stamping for kids working toward Junior Ranger. It's the digital companion to the physical Passport book that's been in NPS visitor centers since 1986 — modernized and made beautiful.
Stampr is made by All Things AI — a small team that builds the tools we wish existed. We've been chasing the All 63 challenge for years and got tired of the dog-eared paper Passport book in the glovebox. We made the digital one we wanted in our pocket.
