Trailfolio: Virtual Hiking

Your daily walks, mapped onto the world's great trails. Replay each day in 3D as your hiker crosses passes, lakes and meadows.

Turn the distance you walk every day into a journey along the world's great long-distance trails.

Trailfolio reads your daily walking distance from Apple Health and moves you along a real trail. Walk 8 km around town, and you'll have hiked 8 km through Yosemite's high country, past glacier-fed lakes and over granite passes. No GPS tracking, no workouts to start: just walk, and open the app to see where your feet have taken you.

REPLAY EVERY DAY Each day's walk becomes a journey you can watch. Your hiker sets off across real 3D terrain, following the trail you covered, and stops at every lake, pass and creature you met along the way to tell you its story.

SIX TRAILS ON THREE CONTINENTS • Teton Crest Trail, Wyoming (64 km), free • W Trek, Torres del Paine, Chile (72 km), free • Milford Track, Fiordland, New Zealand (58 km), free • John Muir Trail, Yosemite to Mount Whitney (340 km) • Wonderland Trail around Mount Rainier (139 km) • Tour du Mont Blanc through France, Italy and Switzerland (166 km)

SEE THE TRAIL IN 3D Follow your hiker across real terrain, with mountains, lakes and passes drawn from open elevation data. Zoom out to see the whole trail and how far you've come.

A FIELD GUIDE THAT FILLS ITSELF More than 200 plants and animals and nearly 140 landmarks wait along the way, each with its own watercolor illustration. Walk past a whitebark pine or a marmot colony and it joins your collection. Finish the trail and you'll have found them all.

TRAIL NOTES AND A DAILY JOURNAL Every day becomes a journal page: how far you went, what you saw, and a postcard you can share. Trail Notes tell the stories behind famous campsites, huts and resupply stops.

DRESS YOUR HIKER Earn points as you walk (1 km = 1 point) and trade them for hats, packs, boots and more. Finish a trail to unlock its commemorative gear.

PRIVATE BY DESIGN Your health data stays on your iPhone. No account, no ads, no tracking. Trailfolio only reads Walking + Running Distance and never writes to Apple Health.

Three trails are free to hike. The John Muir Trail, Wonderland Trail and Tour du Mont Blanc are one-time purchases. Some gear can also be bought individually. There are no subscriptions.
