Grounded
Real trail miles, not guesses
Every distance comes from the same calibrated AT data behind the live map — official 2,197.4-mile frame, anchored to the guidebook.
Scout · The AT app
A field cockpit, not a chatbot.
Scout plans your days, watches the weather, finds your next water and shelter, and turns your own documents into trail-ready decisions — grounded in the same calibrated Appalachian Trail data behind Dad's live map, and honest about what it can't confirm.
App Store and Google Play listings aren't live yet. The waitlist is. We'll email you the day Scout ships.
Source-first
Your docs + Dad’s guide
Scout starts from Dad’s field guide, then layers in the documents and preferences you bring, so its advice is yours — not a generic average.
Offline-aware
Works when signal doesn’t
On-device models keep Scout useful in the backcountry; it connects to a stronger model when you have bars.
Honest
Tells you what to verify
Scout flags what it can’t confirm — water, closures, current conditions — instead of inventing a confident answer that gets you hurt.
What Scout does on trail
A field cockpit, not a chatbot.
Open Scout and you don't get a blinking cursor. You get the next 20 miles, the next water, the next bed, the weather that matters, and a pack check — with the work shown.
On-trail
The next 20 miles
A scrollable look ahead: climbs, descents, shelters, water, road crossings — all from the calibrated official-mile frame behind the map.

Conditions
Weather you can plan against
Trail-segment forecasts so a 5,000-ft ridge gets its own answer, not the nearest town's. Scout flags how stale the read is.
Source: NWS gridpoints + cache timestamp
Hydration
Where the next water is
Sources ordered by distance ahead with a confidence tag — verified, seasonal, or unverified. Scout asks you to confirm before you bet on a spring.
Verification: FarOut/ranger reports cross-checked
Sleep
Shelter and camp options
Upcoming shelters, tent pads, hostels — plus the honest distance math: can you reach the next one before dark, or do you stop short?
Source: ATC shelter list + our own anchor mileage
Effort
Elevation and difficulty
Whites or Pennsylvania flat? Scout reads the silhouette ahead and gives you climb feet, descent feet, and a difficulty take for the section.
Source: USGS elevation per official mile
Loadout
Pack and consumables
Your gear list, base weight, food/water carried, and what should change for the next leg — cold front coming, fuel low, town tomorrow.
Source: your own loadout + Dad's field guide notes
Trail culture
Landmarks & traditions
Half-gallon Challenge, four-state day, the Doyle, the Whites huts, Katahdin sunrise — Scout marks the ritual moments and the miles they live at.

Resupply
Towns and mail drops
Next town off the trail, miles in and out, hostels, post offices, grocery hours — and which mail drop is queued for that stop.
Source: AWOL town tables + your mail-drop plan
Scout works offline-first. On-device models keep it useful when bars drop; it reaches for a stronger cloud model only when you have signal and allow it. No current-condition claim is made without a source or a "verify this" flag.
What that looks like
Example exchanges — illustrative, with real calibrated trail miles.
YouPlan me a 3-day northbound hike from Pine Grove Furnace.
ScoutConservative shape, ~33.5 trail miles over 3 days (~11/day), Pine Grove Furnace (mile ~1,106) finishing at Darlington Shelter:
• Day 1 — Pine Grove Furnace → James Fry Shelter side trail
• Day 2 — James Fry → PA 174 / Boiling Springs (mile 1,125.1) — resupply
• Day 3 — Boiling Springs → Darlington Shelter
Want more miles? I can stretch it to Duncannon (~44.9 mi). Verify shelter water and legal camping against a current guide before you commit.
YouNext resupply heading north?
ScoutFrom Pine Grove Furnace (~mile 1,106), your next on-trail resupply is Boiling Springs at mile 1,125.1 — about 19 trail miles north. Water on the ridge between is seasonal; carry enough to reach a confirmed source.
YouIs the water flowing at that shelter?
ScoutI can't confirm that one is running right now — treat it as unverified until a recent FarOut comment or ranger report says otherwise. Want me to add it to your checklist to confirm before you rely on it?
