Topographic maps & tools that work with no signal. NOTE: Satellite SMS feature is used outside of this app via Messages. This companion app is for using and downloading maps and tools for offline use, as well as using the Ask Deadzone AI assistant with internet. Deadzone is built for backcountry travel where the map app on your phone gives up. Download a North American topographic basemap — 10-meter contours, 94,000 named summits, light and OLED-black "Night Ops" themes, and navigate offline once you're out of service. MAP DATA OUTDOOR PROS ACTUALLY READ Layer the data that matters, every feature tappable for detail: - Motorized routes: USFS Motor Vehicle Use Maps, Forest Service roads & trails, BLM travel-management routes - Public lands: ownership and jurisdiction (PAD-US), designated wilderness, National Park trails - Water: rivers and lakes, coastal and inland depth contours, live tides and river gauges - Hazards: active wildfire perimeters, cell-coverage dead zones - Trails: OpenStreetMap and state OHV systems - And much more TERRAIN TOOLS Tools that compute against real elevation data, on-device and offline: - Route profile — elevation gain and loss along any route - Viewshed — everything visible from a point - Sight line — whether you have a clear view between two points - Radio line-of-sight — whether two stations can reach each other over the terrain - Sun & shade — where shadows fall at any date and time - Plus wind, area and distance measurement, coordinate conversion, and geofence alerts - And more ASK DEADZONE An AI assistant tuned for the outdoors. Ask about weather, trail conditions, water sources, or gear, and get answers grounded in live data from the NWS, USGS, the National Park Service, and more, not guesswork. Tap any map feature to ask a follow-up question about that exact spot. PLAN AND RECORD Build multi-day trips with waypoints, import and export GPX, get a briefing the evening before you leave, and record your track on the trail. FIELD REFERENCE Wilderness first-aid protocols, written for fast reading when it counts. PART OF THE DEADZONE PLATFORM Deadzone also bridges satellite SMS to the same AI — text questions from anywhere with no cell service (T-Mobile T-Satellite, Garmin inReach, and compatible devices). The app is your planning and navigation companion to that service. — — — Deadzone requires an account; create one and choose a plan at getdeadzone.io. Plans start at $5.99/month and include full offline maps and every overlay. Maps, tools, and field references are for informational planning only and are not a substitute for professional judgment, official sources, or emergency services. Deadzone is not an emergency service; in a life-threatening situation, contact 911 or a satellite SOS / personal locator beacon. © 2026 Obsidian Design, LLC ## Key features - Offline topographic maps - AI outdoor assistant - Terrain analysis tools - Route planning and recording - Field reference guides - Motorized and public land overlays ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/deadzone-maps-and-satellite-ai/id6762406863/reviews.md ### 5/5 — Best Off Grid Option *2026-06-06* If you spend a lot of time outdoors without cell service then this is definitely the app you need. It’s more than just downloadable maps, although its maps features are incredible and super detailed. It’s a powerful AI chat bot you can use with JUST SATELLITE.

New OSM Roads overlay adds much broader coverage at more zoom levels. Tap a road and the whole route highlights, with a new "What road am I on?" indicator while navigating. New Open Now / Likely Closed status combining seasonal closures, fire perimeters, and community reports. Community Road Reports (new): Report and view current conditions — mud, snow, downed trees, gates, closures. Confirm, clear, or flag others' reports. Anonymous, and fades as it ages. Camping: Dispersed camping "Smart Spots" now covers the Lower 48, with improved accuracy. Ask Deadzone finds verified campsites nationwide. Map & Fixes: Cleaner map controls and more legible labels; satellite loads faster. Fixed saved overlays not restoring on reinstall, a Settings profile-save error, and road names in tap info and directions. ### 1.4 — 2026-06-28 New layers, a sharper Ask Deadzone, and a more reliable track recorder. NEW • Satellite Hybrid basemap — high-res aerial imagery with topo contours on top. Open the layer menu and tap Satellite. (Idaho first; more states rolling out.) • Land Ownership overlay — see whose ground you're on: Forest Service, BLM, state, and private inholdings, with tap-to-identify and a plain-language access read. • True / Magnetic bearings — a new Display setting flips every heading, azimuth, and wind direction between true and magnetic north, so the app reads like your baseplate compass (World Magnetic Model 2025). IMPROVED • Ask Deadzone is smarter in the field — "find me a dispersed campsite" and "what's here?" now answer from our own map data: legal land, flat ground, water, road access, line-of-sight to a peak, sun exposure, dark-sky quality, and cell dead zones. • The "Suitable" dispersed-camp overlay now covers Idaho and Washington. FIXED • Tapping the recording Live Activity now reopens the recorder with your track still running, instead of dropping the session. • Saving a track's share card to Photos no longer crashes. • Signing in with an email that has no account now offers to create one, instead of waiting forever for a link. ### 1.3 — 2026-06-06 New — True / Magnetic north toggle. Switch every bearing, heading, and azimuth between true and magnetic north so the app reads like your baseplate compass. Powered by an on-device World Magnetic Model (WMM2025) — works with zero signal. Flip it in Settings → Display → Bearings. New — Dispersed camping overlay (Idaho, beta). Scout legal dispersed campsites on USFS/BLM land, scored for terrain and access. Idaho first; more states rolling out. Smarter Ask Deadzone. Tap a river or tide station and Deadzone now reasons from the live gauge flow or tide reading — real numbers, not guesses. Tap any feature and it knows what else you're standing in (a road inside a wilderness, a trail beside a named river) for answers with real context. Cleaner map info. Reclaimed wasted space at the top of the tap-for-info sheet so feature details show up faster. Radio Line-of-Sight polish. Clear links now read green across the coverage map, path, and legend. Plus assorted fixes and refinements. ### 1.2 — 2026-06-05 No release notes. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
