Artifact Tracer · offline GPS field marker

It's under here somewhere.

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 and a note, and the compass walks you back to it. Every time. Offline. Yours for $15.99, forever.

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.

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.

Fall blowout · spring startup

The sprinkler heads that sank

Heads bury themselves under thatch and landscaping. The irrigation guy charges by the hour while you both stomp around looking.

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.

"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 one of these is a real bill that exists because a location wasn't written down. You don't need any of them — you were standing right there when you knew where it was.

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 Tracer is built around that truth: average the fix, keep a human note, let the compass do the last stretch.

Step · Mark

Stand on it. Mark it.

Tracer re-averages GPS readings while you stand on the spot, and saves a relative note with every mark — "11 ft NE of the maple." Photo it, 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 your note finishes the last step to the exact spot.

Live heading + distance + your own 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 any time — it works in every mapping tool on earth.

One tool, every buried thing

If you'll ever need to find it again, mark it now.

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 hide. 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 ask you to keep access to your own property.

▲ 0 ft — you're standing on it

Mark it once. Find it again.
