Navigation that never phones home.

A complete topographic navigation system that lives on your iPhone. Every map, every trail, every instrument — encrypted, offline, yours. And when even GPS is gone, it finds you by the stars.

01 — THE MAP IS THE PROOF

A hand-built renderer, not a reskinned template.

Every pixel below is drawn by a custom Metal engine — GPU hillshade in four relief styles, contour lines traced live from the same elevation data, street labels placed with survey-grade discipline. Zero third-party code. It works identically at the trailhead and in airplane mode.

02 — EVERYTHING, OFFLINE

Airplane mode is its natural habitat.

Search, routing, elevation, even driving directions run entirely from encrypted packs on the phone. Nothing here needs a bar of signal — not one feature degrades when the network disappears.

SEARCH

Down to the rural house number

Addresses, places, and points of interest — parcel-data deep. Reverse geocoding included. All from the pack.

TRAILS

Routes rated for your legs

A custom router with elevation profiles and difficulty calibrated to the fitness level you set — not a generic average.

DRIVING

A to B with zero towers

The road graph rides inside the pack. Car or on foot, the route computes on the phone.

PIN CARD

Coordinates that mean it

Long-press anywhere: position, true elevation from the terrain model, live range and bearing from where you stand.

WAYPOINTS

Mark it, keep it, find it again

Waypoints and saved routes that survive map updates — plans, not fragile polylines.

NIGHT

Built for 2 a.m.

A skinnable theme system with a true night mode — off, on, or following the system, on every map style.

03 — THE WORLD, STANDING UP

One tap, and the map becomes terrain you can fly.

Real forests, grown from satellites

Ground cover is synthesized on the GPU from 10-meter satellite land-cover — forest, sand, rock, and snow that match the world, not a photo texture. Real buildings extrude to their true heights.

Walk tomorrow's hike tonight

Fly a saved route on rails or drop to eye level and walk it — the trail draped on the terrain ahead of you, scrubbable, at your pace.

A flight stick anyone can use

Drag to look, one thumb to fly, a slider that owns your altitude. From helicopter height to boot height without a tutorial.

And a camera

Vista Studio photographs the 3D horizon and renders it in ten styles — WPA poster, ink sketch, blueprint, watercolor — full-res, shareable, offline.

04 — THE INSTRUMENT DECK

When GPS dies, the sky still works. FIELD BETA

Lay the phone on the ground under open sky and it identifies the stars with its camera and solves your position — no signal, no GPS, no network. By day: the sun, a shadow, or the shape of the horizon. A technique sailors needed a sextant, an almanac, and years of practice for.

The honesty ring. Every fix carries an error ring calibrated against GPS truth — designed to over-warn, never to flatter. A fix it can't stand behind is refused, not mapped. The record ground fix landed 346 m from truth — inside a ring the instrument had honestly called ±4.5 km.

05 — CAMPSITES

A million campsites, zero bars required.

The most complete legally-compiled campsite database anywhere — federal, state, and international sources merged into one offline layer, license provenance kept straight the whole way. Cards carry the phone number and the reservation link, ready the moment you're back in range. Rolling out to the packs now.

06 — YOURS MEANS YOURS

No cloud. No account. No one watching.

Map packs are sealed with authenticated encryption and read through a custom decrypting layer — the keys never leave your device. There is no login, no analytics, no telemetry. Your maps and your movements are nobody's data.

07 — ON YOUR WRIST

The Apple Watch stands watch with you.

NIGHT WATCH

Silent overnight star fixes

Arm the night watch and sleep. The wrist card tracks bursts, drift, and the dawn ETA; a tap pattern tells you to spin the phone a quarter turn — no light, no sound, no ruined night vision.

WALK RECORDER

Fix by walking, hands free

One button, drop your arm, walk. The watch streams calibrated distance while the phone matches your elevation trace against the terrain — and draws the breadcrumb home.
