What ParkStamp is and what it does.
What is ParkStamp?
ParkStamp is a digital StampBook for America's 63 national parks. You record every park you visit for free, and you can collect original WPA-style poster art for the ones you love. Your StampBook fills in over time with dates, stats, streaks, and badges — a lasting record of where you've been and how far you still have to go.
Is ParkStamp free?
Yes. Browsing all 63 parks, stamping every visit, your full StampBook, journals, stats, badges, and the share poster are free forever. The full-color stamp art is the only paid part, and it is an optional one-time purchase — never a subscription.
What's the difference between Stamped and Collected?
A stamped park is the free record of your visit — dated and saved to your StampBook, counted in all your stats. Collected means you've also unlocked that park's original full-color poster art. You can stamp every park without ever collecting one; the art is purely the part you choose to own.
Is ParkStamp on iPhone and Android?
Both. ParkStamp is free on the App Store and Google Play, and because your StampBook is tied to your account rather than your phone, you can switch platforms and keep everything.
Is ParkStamp affiliated with the National Park Service?
No. ParkStamp is an independent product built on official public data from the National Park Service, but it is not affiliated with, sponsored by, or endorsed by the NPS or any government agency.
I collect ink cancellation stamps at visitor centers. Does ParkStamp replace that?
No, and it isn't trying to. If you carry the paper book and collect cancellations at visitor centers, keep doing it. ParkStamp is the version that lives on your phone: it remembers the dates for you, works even when you forgot the book, and can read your old photos to find parks you visited years before you started keeping count.
