iPhone

Log hikes and scratch off the places you have earned. Your entire hiking life as a single beautiful map you scratch off. Log a national park or a state in under ten seconds. The map fills in with warm terrain color. A stone gets added to your cairn. The widget keeps your map on your home screen between trips. START WITH EVERYWHERE YOU HAVE BEEN No trip planned? No problem. Tap every park and state you have ever visited and watch two decades of trips become one map in ninety seconds. No dates needed. THE MAP IS THE POINT Dark topo field. States fill as terrain. Parks pin as collectible patch stamps. Pinch into regions. A counter that reads 28 of 63 parks and means something. BUILT TO KEEP, NOT TO CHECK No streaks. No guilt. A collection, not a chore. Stamp badges for milestones and region sets like Utah's Mighty 5. A lifetime recap from day one, and a year recap every December. SHARE THE PROOF Every log and milestone offers a share card with your map on it, sized for stories and posts, rendered on your device. YOURS, PRIVATELY No account. No tracking you around the web. Your logs live on your device and sync privately through iCloud. Export everything as JSON anytime. Two collections at launch: all 63 U.S. National Parks and all 50 states.
