Cairn: Hike Log & Scratch Map
63 parks. Scratch-off map.
Free · Designed for iPad. Not verified for macOS.
Scratch off every national park and state you have visited. One map, one cairn, no streak guilt.
Your hiking life as one scratch-off map.
Log a U.S. national park or state in seconds. The topo map fills with warm color. A stone joins your cairn. A home-screen widget keeps progress visible between trips.
START WITH EVERYWHERE YOU HAVE BEEN
No trip planned? Tap every park and state you have ever visited and turn years of travel into one map in about ninety seconds. Dates optional.
THE MAP IS THE POINT
Dark topo field. States fill as terrain. Parks appear as collectible stamps. Pinch into regions. A counter like 28 of 63 parks that means something.
BUILT TO KEEP, NOT TO CHECK
No streaks. No guilt. Milestone badges and region sets like Utah's Mighty 5. Year recap every December.
