HIKE WITH FRIENDS (New!)
• Add hiking friends with a simple friend code
• See each other's progress — sections, miles, and percent complete
• Shared Gaps shows the sections you all still need, so you can plan hikes that move everyone closer to 900 miles
CURRENT PARK CONDITIONS

• Current weather at Gatlinburg, Clingmans Dome, Cades Cove, and Cherokee
• Real-time river levels and air quality

PLAN SMARTER
• AI Route Planner builds custom hikes from your real trail history
• AI trail summaries distill what other hikers are seeing on trail
• Trailhead Hub Explorer: parking, facilities, and closures for all 10 hubs
• Switch between OpenStreetMap and NPS base layers on the map
REMEMBER EVERY MILE
• Attach photos to each hike for a growing digital scrapbook
• Automatic historical weather captured for every entry

Whether you're on mile 5 or mile 850, Smoky Mountains 900 keeps your journey organized, social, and unforgettable.
This app is easy to use. I was able to download create an account and import my tracking sheet within less than five minutes. I was then able to easily find trails that I had not completed on the spreadsheet and complete them within the app, highly recommend this app. I plan on using this app as o work toward completion of the 900 going forward.
Exactly What 900 Miler Seekers Needed!

This app has saved me & hiking buddies countless hours we previously spent comparing maps to find shared gaps in our quest! And too many other useful features to list!
Game Changer!

This is going to make this so much easier to keep track. So glad to have this app.
Fixed: Progress you removed could reappear on its own if you use the app
on more than one device. Sections you un-mark now stay un-marked, and the
change shows up on your other device without a manual re-sync.
Fixed: The sync options in Account Settings could remove a large amount of
data when run on a device that hadn't finished syncing. They now recognise
that and stop, with an explanation, instead of deleting anything.
Fixed: Hatcher Mountain Trail and Juney Whank Falls Trail weren't counting
toward your progress. If you'd hiked either one, they showed as still
needed in Shared Gaps and 3.1 miles were missing from your total. Both are
corrected automatically.
Improved: The trail list now keeps your place when you open a trail and
come back, along with any search or filter you had set.
Improved: The app tour now covers Conditions, Friends and Shared Gaps, and
shareable progress images. Replay it anytime from Account Settings.
