January · water everywhere
The shutoff valve, under snow
A pipe lets go at 6pm. The main shutoff is somewhere under four hundred square feet of white. Every minute of guessing is water in the wall.
Artifact Tracker · offline GPS field marker
Mark Once.
Find It Again
The shutoff valve, the trail cam, the property pin, the thing you buried on purpose — you knew exactly where it was eight months ago. Mark it once with re-averaged GPS, a note and a photo of the spot, and the compass walks you back to it. Offline. Yours from $29.
No account · No signal needed · No cloud · Not $99/month
You already know this feeling
Four times a year, your land hides something from you.
Camera pull · end of season
The trail cams you forgot
Cameras get moved all season. Come pull time, you're re-walking every ridge line trying to remember which tree — and some stay out there.
Fence quote · property dispute
The corner pin from the survey
The surveyor found it once — that cost you real money. The flag is long gone, and the neighbor is confident about your fence line.
Fall blowout · spring startup
The sprinkler heads that sank
Heads bury themselves under thatch and landscaping. You end up paying someone by the hour while you both stomp around looking.
"I was surprised several times by finding cameras on trees that I'd forgotten about." — hunter, DeerBuilder forum, "Keeping track of all your trail cameras"
"I keep a spreadsheet on my laptop, that I use to track the locations of my trail cameras." — the current state of the art, same thread
The price of not knowing
Guessing is the expensive option.
Every line here is a bill somebody paid because a location wasn't written down. You don't need any of them — you were standing on the exact spot, once.

Honest about the hard part
Phone GPS drifts. So we don't trust it alone.
A single GPS snapshot can be off by 10–30 feet — anyone who says otherwise is selling you something. Artifact Tracker is built around that truth: average the fix, keep a human note and a photo, let the compass do the last stretch.
Step · Mark
Stand on it. Mark it.
Tracker re-averages GPS readings while you stand on the spot, and saves a relative note with every mark — "11 ft NE of the maple." Snap a photo of the spot, tag it, done in 20 seconds.
GPS·AVG + relative note + category + photo
Step · Walk back
Follow the needle.
Next season, open the mark. A live compass and distance readout walk you across the field — 87 ft, 40, 12 — and when you arrive, the photo you took and your note are right there on screen to finish the last few feet.
Live heading + distance + your photo + your words
Step · Keep
It's your data. Literally.
One offline file on your device. No account, no cloud, no subscription. Draw zones, organize by property, and export GPX · KML · GeoJSON · CSV any time — it works in every mapping tool on earth.
Offline file · GPX/KML in and out · multi-property
"In the best scenario, you will get an accuracy of 10 to 15 feet, but obstruction can add that number up to 30 feet or more." — SNAP! Geocaching, "Why are my coordinates so far off?" — the drift every mark here is built to survive
Not a mockup
This is the tool.
Real screens, straight from the working tool — the same one in the free demo, so you can hold it before you buy it.
No lock-in — filmed, not promised
Your marks come to life anywhere.
One uncut take, start to finish: back up everything with one tap, then hand your marks to any map program on earth. Watch a real export come alive in geojson.io — pins, zone, field notes, all of it.
GPX → Garmin · Gaia · onX · Caltopo KML → Google Earth GeoJSON → QGIS · Mapbox CSV → any spreadsheet
The arrows run both ways. Coming from Garmin, onX, Gaia or Google Earth? Import your GPX, KML or GeoJSON and bring every mark with you — waypoints become marks, tracks and boundaries become zones, and you see a preview before a single thing is saved.

"Tap a location anywhere on the map to add your own Waypoints for campsites, rock crawl areas, non-ethanol fuel stations or where you parked the trailer." — from a subscription offroad-mapping app's own feature list. Even they know this pain — they just charge for it every year.
Works with zero bars
It's your land, not a coverage map. Everything runs on-device — mark and walk back with no signal at all.
Nobody else's cloud
These are the coordinates of everything you own — and a few things only you know about. They never leave your phone. That's a security decision, not a feature gap.
No account. Ever.
Open the file, use the tool. Nothing to sign into, nothing to expire, nothing to get breached.
Bought once, yours for keeps
The file is yours like a hammer is yours. No renewal email will ever charge you for access to your own property.
Before your card comes out
Fair questions.
- Is phone GPS accurate enough to find a buried valve or marker?
- A single GPS snapshot is not — that is exactly why Artifact Tracker re-averages readings while you stand on the spot, and saves a relative note like "11 ft NE of the maple" with every mark. The compass gets you to the last few feet; your note finishes the job.
- Can I add a photo to a mark?
- Yes — every mark can carry a photo of the spot. Snap it while you're standing there; it's saved on your phone with the mark and never uploaded anywhere. When the compass walks you back, the photo is on the arrival screen, so the last few feet are a picture, not a guess. Photos ride along in your one-tap backup too.
- Does it need an account or signal in the field?
- No account and no server, ever. It runs offline in your browser as one file you own. Solo and Homestead are one payment, no subscription, yours to keep; Crew is an annual license for outfits — and every tier keeps your locations on your device, with GPX/KML export whenever you want.
- How is this different from the subscription field-mapping apps?
- The comparable apps are field-operations platforms built for utility crews: a small free tier, then $99+ per month, with your asset locations in their cloud. Artifact Tracker starts at $29 once — Solo covers one site, Homestead covers unlimited sites for $39, both yours to keep. For outfits, Crew Annual is $299/yr: five seats, unlimited sites, branded reports, the Invoice & Payment Tracker included. Every tier keeps every coordinate on your own device.
- What happens if our Crew license lapses?
- Every seated device keeps working. Nothing you marked is ever locked away and nothing stops opening. A lapsed license only stops adding new devices — renewing reopens that. Your data was never on our servers to begin with, so there is nothing to lose.
- How do I get it after I pay?
- Checkout runs through Stripe's secure checkout — we never see your card. Minutes later an email arrives with your personalized copy and unlock link: open it on your phone and your computer and you're marking. No app store, no installer, nothing to sign up for.
- How do I know it'll work on my ground?
- Find out before you pay: the free demo is the real tool, not a tour. Walk out and mark your actual valve, then walk back to it — under your trees, with your signal, on your phone. Nothing expires and there's no account, so you'll know before a dollar moves. That's also why sales are final: you've already watched it work.
