OurHike is an offline-first topo map for the AT, built for the places where a map that needs signal is no map at all. Paid memberships are intended to fund the ATC and the volunteer clubs who keep the trail open.
This is a beta, and worth treating as one. It has not
been field-tested across the trail. Carry a paper map and a compass,
tell someone your plan, and don't make a navigation decision you
couldn't make without a phone.
Install it
OurHike is already installed. Open it from your home screen.
- Open the app itself — OurHike. Installing has to be done from there, not from this page.
- Once it’s open, go to the Downloads tab. It shows the install button, or the exact steps for your phone.
- Then come back here for what to do next.
On iPhone, use Safari. Other iOS browsers cannot
install a web app at all. iOS can also clear a web app’s
stored data when the device runs short on space, and the offline
map is a large download — so test it before a trip, and check the
map is still there before you set off.
It runs in a desktop browser for a look around, but it’s built for a phone. Open this page on your phone to install it properly.
Once it's installed
- Open the app and go through the short first-run screens.
- Pick how much map detail you want — the only real decision.
- On Downloads, tap Download the map while you're on wifi. Trail lines come first, then the topo background.
- Test it before you go. Turn on airplane mode and check the map still draws.

A dropped download resumes instead of starting over.
If trailhead wifi gives out at 90%, you haven't lost the 90%.
What works today
- The full topo map offline, with the trail drawn by blaze colour
- Your position and mile marker along the trail
- Shelters, water, campsites and resupply — searchable with no signal
- Reporting a problem, saved on your phone, no account needed
Not yet
- Accounts and syncing, so reports stay on your phone for now
- The elevation profile
- The wrong-way alert — built, but its thresholds are unvalidated, so it's deliberately switched off rather than shipped as a safety feature that might not work
