Stampr Passport
Read full descriptionHide full description
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. Questions or feedback?

DogMaps

Every dog person knows the feeling. You're two hours down the highway, the dog is doing the thing in the back seat, and you have no idea where the next decent place to stop actually is. Dog Maps answers that in one tap. I NEED TO STOP One button. Instantly ranked places to pull over near you, sorted by what's genuinely close and genuinely usable.. including dog parks, trailheads, rest areas, and open public land. No scrolling, no guessing, no pulling into a gas station hoping for a patch of grass. WHAT YOU'LL FIND - 18,000+ dog parks across the country - 10,000+ trailheads - 3,700+ highway rest areas - 24/7 emergency vets with one-tap calling - Regular vets and clinics - Beaches, with their actual leash rules - Off-leash and on-leash areas, labeled honestly THE PUBLIC LAND MAP This is the part nobody else does properly. Dog Maps draws National Forest, BLM, National Park, state and local land right on the map, so you can see at a glance where you're actually allowed to take your dog. And it only paints land that's open.. closed and restricted parcels are never shown as usable. If it's green, you can probably be there. TRIP PLANNER Tell it where you're headed and when you're leaving. It builds a break schedule along the route at the cadence you pick, shows what each detour costs in minutes rather than miles, and hands the whole multi-stop route to Apple Maps when you're ready to drive. WHAT'S BETWEEN YOU AND THERE Active wildfire perimeters and National Weather Service warnings overlay the map, so you can see what's on your route before you commit to it. Hazard data can lag.. always confirm urgent conditions with official sources. DOG MAPS PRO A single one-time purchase unlocks unlimited trip planning, the full public land map, surface water layers, and every hazard overlay. No subscription, ever. BUILT THE WAY IT SHOULD BE No account. No sign-up. No reviews to wade through, no feed, no social anything. It opens to a map and it tells you where to go. Made by one person who drives a lot, with dogs.

Verdict
The clearest difference is in-app purchases: Stampr Passport at none against DogMaps's 1. On price, ads, device support and iOS requirement there is nothing between them.
