01 / What's on it

A library that leaves home with you.

The core library lives on the device. Open your maps, read a reference or pull up a PDF without waiting for a connection.

Maps of the West

Offline topo maps in OsmAnd for mountain trips, desert roads and time beyond cell coverage.

Knowledge on hand

Offline Wikipedia plus survival, medical and foraging references through Kiwix.

Books & field guides

PDFs and books in an easy-to-reach offline library. Useful reading without another login.

Planned map coverage: Utah, Idaho, Nevada, Colorado, Wyoming, Montana, New Mexico, Oregon, Washington and California. Final sale-library contents will be confirmed before launch.

Built around time outside

Real tools. Ready to open.

No concept screens. A closer look at the tools on our test phone.

Framed real screenshots of field manuals and water references — Field references, already on the phone.

Framed real screenshots of Signal for help and the red night theme — Make yourself seen. No rescue connection implied.

Actual app screens in illustrative, hardware-neutral frames. Reference tools are not medical care or a rescue service.

02 / Built for the field

Less background junk.
More useful tools.

The launch phone is built around the Samsung Galaxy XCover 6 Pro, a rugged Android with a removable battery.

We remove unnecessary apps and tune background activity for battery life. Survival Hub keeps offline tools together on a simple launcher.

No cloud connection is needed for the preloaded library. Optional updates need a connection.

Battery testing in progress

Target: up to two weeks
on standby.*

We are verifying this target with testing. It is not a measured or guaranteed result yet.

*Survival Mode: airplane mode, power-saving settings and minimal use. Battery condition, settings, screen time and GPS use affect runtime. Continuous navigation is not standby.

03 / Who it's for

For the places where bars disappear.

Utah families building a go-bag. Hunters heading into the mountains. Desert travelers. Anyone who wants a useful backup when the internet isn't an option.

Keep it with your field gear. Learn the tools before you need them. Carry paper maps and a power plan, too.

04 / Find your setup

One idea. A few ways to carry it.

Planned options. Pricing and availability will be announced before orders open.

05 / Good questions

Before you pack it.

Does it need service, Wi-Fi or a subscription?

Not for the core preloaded library and maps. Those work offline with no subscription. Downloads and updates require an internet connection.

Is this a satellite phone or an emergency beacon?

No. Offline reference tools do not provide communication or rescue service. Carry appropriate emergency communication equipment for your trip.

What is Survival Hub?

Our Android launcher that brings the offline maps, Kiwix library, PDFs and books together on a simple home screen. Dark Grid Hub is the business behind it.

Can I order one now?

Not yet. Join the waitlist for launch news, confirmed library contents, device details and pricing. There is no payment or reservation at this stage.

Can I rely on the medical references for treatment?

They are reference material, not a substitute for first-aid training, professional medical advice or emergency care.
