more Map fixes: Hannah Mountain, Scott Mountain (shows only the open 0.2 mi), Jakes Creek and Balsam Mountain now draw in the right places. Hikers who've completed every section now see 100%.
1.9.2 Oct 23
Fixes a crash when opening the app on iOS 27. Sorry about that — everything from 1.9 is here and working.
1.9.1 Oct 18
What's new in 1.9
CLOSURES ON YOUR MAP
Trails the National Park Service has closed now show on your trail map: long dashes for fully closed, dots for partly closed. Tap a trail for the official NPS notice and when it was last checked. Turn closures on or off from the map legend. No marking doesn't mean a trail is open, so always check NPS before you hike.
THEIR MAP
In Shared Gaps, pick one friend and choose Their Map to see the trails they've hiked, so you can plan where to go together. The List / Map switch is easier to find, too.
FRIENDS
If two of your friends use the same name, each now shows when they last logged a hike, so you can tell them apart. You'll also be asked before adding a second friend with a name you already have.
SIGNING IN
The app remembers how you last signed in on this phone. If a new account would be created on a phone that already has your hikes, it checks with you first, which helps avoid ending up with two accounts.
SPREADSHEET IMPORT
Imports are more accurate: rows without a full date are listed for you instead of guessed, unclear trail names are never matched to the wrong trail, and older hikes are accepted. Have years of past hikes, your own spreadsheet layout, or a CSV? Enter or import them on a computer at smokies900.org/progress and they'll show up in the app.
FIXES AND IMPROVEMENTS
• Your community name is restored when you sign in on a new phone
• The friends list offers a retry instead of looking empty when it can't load
• Clearer messages if the app can't start or share images are made too often
• Security update to the app's underlying framework
1.9 Oct 14
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.
1.8.1 Aug 17
Turn your progress into something worth posting.
New — Shareable Progress Images:
• A progress map of every section you've finished, drawn on the official NPS trail map and color-coded by the year you hiked it
• Milestone cards for your first completed trail, 100/250/400/500/750 miles, and finishing all 325 sections
• Preview any image full size before you share it, then send it straight to a share sheet or save it
Improved:
• Everything you hiked before 2023 now shares a single color on the map, so your recent years stand out
• Conditions now shows that trail closures are checked against NPS every day
Fixed:
• Trail closures no longer warn that data "may be out of date" when NPS simply hasn't posted changes
• A milestone celebration no longer stacks on top of the welcome message
Thanks for hiking with us!
1.8 Jul 31
This update adds official NPS trail closure information throughout the app.
New — Trail Closures:
• See NPS closure and caution notices right on the trail page, trail cards, and Shared Gaps — both list and map view
• Each notice shows the full official wording from NPS, when it was last checked, and a link to the source
• The AI Route Planner now checks current NPS closures before suggesting a hike — it won't route you onto a closed trail, and will flag any caution notices along the way
Thanks for hiking with us — always confirm current conditions with NPS before you head out.
1.7.3 Jul 26
This update makes planning group hikes easier and fixes a date display issue.
New — Shared Gaps Map:
• See the sections you and your friends still need on a map, not just a list
• Color-coded by who can join: green where you all still need it, blue where a friend has already done it and can come along as a guide
• Switch between OpenStreetMap and the NPS park map
Fixed:
• Trail condition reports now keep their correct original dates instead of appearing freshly posted after a sync
Thanks for hiking with us!
1.7.2 Jul 7
Friends is here — team up and finish the 900 together!
• Add hiking friends with a simple friend code — swap codes and you're connected instantly
• See each other's progress: sections completed, miles, and percent of the park done
• Shared Gaps — pick a group of friends and see the sections you all still need, so you can plan your next hike together
• "I Need" view shows which friends have already done a section, for when someone tags along on a re-hike
Also in this update:
• Fixed: logging conditions on a multi-section trail no longer posts duplicate community reports
• Fixed: progress logged while signed out now syncs automatically when you sign in

Trail detail pages now show an AI-generated summary synthesizing recent community condition reports — a quick read before you head out.
Community Conditions in Route Planner
The AI Route Planner now factors in recent community trail reports when building recommendations, not just your personal history.
Update Your Trail Conditions
Already logged a section? A new "Update conditions" prompt lets you quickly edit your report without hunting for the form. Tap a completed section and it scrolls you right to it.
Data & Sync Tools
Account Settings has a new Data & Sync section with clearer descriptions of when to use each tool, plus a new Reset Local Database button — useful if the app is misbehaving. Your cloud backup is always safe; just follow up with Force Re-Sync to restore.
