Bring the campsites you have already found. The water that was actually running, the mines worth the detour, the hot springs, the two‑tracks you want to remember next season. Most apps get slow and unhelpful a few hundred pins in — this one is built for tens of thousands of them, and it goes on your phone for the places the signal does not.
What it does
- Room for all of your waypoints. Import GeoJSON, GPX or KML, or drop them as you go. Nested folders, search, filters and bulk edits keep them findable at a scale most apps give up at — it was built against a working collection of more than 23,000. The only cap is the storage limit on your device.
- Whole states offline, not just one trip. Pull a state down over Wi‑Fi and it stays on the device — terrain, forest roads, trails and points. Edit in the field with no signal at all; it catches up when you are back in range.
- Roads by grade. Paved, dirt, 4WD and trail — including the forest roads most maps leave as one undifferentiated tangle. One scheme across the whole map, so you read the road rather than decode a legend.
- Your data stays yours. Export the whole thing whenever you like, in the usual formats. It is kept private, and every save is a version you can roll back to yourself — nothing is ever one wrong tap from gone.
- Phone, laptop, desktop — one map. Plan on a big screen, edit from the driver’s seat. No app store and nothing to install — it is a website that happens to work offline.
Where it stands
Not open for signups yet. It’s being used and tested on real trips first, and new accounts are invite‑only until that settles. There’s nothing to sign up for here on purpose — no waiting list, no email capture.

Coverage
The Western US only, for now. Eleven states — Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming — with topography, forest roads, trails and points of interest. Outside those, there is no map yet. The lower‑48 is the direction of travel, not a promise with a date on it.
