These ten apps cover different backpacking needs rather than ten interchangeable navigation tools. Pair a downloaded map with current weather and access information; remote satellite messaging requires compatible hardware and service, not just an app. Rankings reflect feature fit, not hands-on comparative testing.

Maker
Trailbehind, INC.
Gaia GPS combines topographic mapping, route planning, and GPS tracking in a versatile backpacking tool. Its paid offline maps make it the strongest all-round choice here for hikers who want more than a trail directory.
Its map collection includes topographic, public-land, and weather information. Premium adds access to more than 300 maps and the National Geographic collection.
On the trail
Download the maps you need before leaving service. GPS tracking, waypoints, and distance and elevation monitoring help you follow your trip.
Trade-offs
Offline downloads sit behind a paid subscription. The breadth of maps also means spending time choosing layers before departure.
Who should choose it
Choose Gaia for varied backpacking routes and detailed pre-trip mapping. Practice downloading and following a route before relying on it remotely.

Maker
CalTopo LLC
CalTopo brings detailed terrain analysis and shared-map planning to a mobile navigation app. It is especially appealing for backpackers who want to examine terrain rather than simply follow a published trail.
Available layers include slope-angle shading, shaded relief, public lands, and several topographic sources. Weather, snow, and water information support pre-trip assessment.
Field navigation
The app can download maps and layers for offline use. GPS location tracking works without cellular service, while online changes sync between devices.
Trade-offs
The range of mapping layers rewards study before a trip. Slope shading and forecasts are planning aids, not guarantees of safe terrain or conditions.
Who should choose it
Choose CalTopo for complex itineraries and collaborative planning. Build and test your offline map before leaving reception.

Yes — downloaded guides
Maker
Atlas Guides DE, Inc.
FarOut, formerly Guthook, packages long-distance routes as downloadable navigational guides. Its waypoint information makes it particularly useful for following established thru-hikes and planning daily logistics.
FarOut partners with trail organizations, authors, and publishers for route data. Guides include junctions, water sources, road crossings, and town information.
On-route usefulness
Downloaded guides provide trail data offline. The waypoint-focused approach helps organize navigation around practical stops along a covered route.
Trade-offs
Its usefulness depends on whether it offers a guide for your itinerary. Check-ins should not be confused with a standalone satellite SOS service.
Who should choose it
Choose FarOut when your long-distance route has a dedicated guide. Buy that guide outright or consider Unlimited if you need several routes.

Maker
onXmaps, Inc.
onX Backcountry combines trail planning with 3D terrain, offline mapping, and land-access information. Its activity-specific tools suit backpackers who also climb, bike, or ski.
The app offers LiDAR topographic views, slope information, and custom waypoints. Private-land details and recent satellite imagery are identified as Elite features.
Offline use
Download 3D maps before losing service. Tracking and route-building tools help connect the plan you studied at home with your progress outside.
Trade-offs
Useful features are split across paid membership tiers. An SOS add-on should not be assumed to give an ordinary phone satellite connectivity.
Who should choose it
Choose onX for visual terrain planning and mixed outdoor pursuits. Confirm the map coverage and membership features needed for your destination.

Maker
Avenza Systems Inc.
Avenza Maps puts your GPS position on downloaded publisher maps and supported geospatial files. It is a useful choice when an agency or mapmaker supplies the exact map you want to carry.
The Map Store includes maps from publishers such as National Geographic and US land agencies. Supported imports include PDF, GeoPDF, and GeoTIFF mapping files.
Offline navigation
Downloaded maps show your GPS position without service. Track recording, placemarks, photographs, and measurement tools add field context.
Trade-offs
Some maps cost extra, and subscription tiers affect import and professional tools. A map-based workflow is different from a seamless trail-discovery directory.
Who should choose it
Choose Avenza when you already know the publisher or agency map you need. Check its coverage and edition before using it on a trip.

Maker
Organic Maps OU
Organic Maps offers free offline mapping and navigation based on OpenStreetMap. It is a strong budget option for backpackers who value privacy and straightforward downloaded maps.
Downloaded regions support offline search and navigation. Hiking paths, contour information, and outdoor map styles help put routes in context.
Navigation tools
The app supports walking and cycling routes as well as driving directions. Track recording and route import and export help move trip data between tools.
Trade-offs
Map detail reflects OpenStreetMap contributions and varies by location. This is not a specialist trail guide or a source of guaranteed current closure information.
Who should choose it
Choose Organic Maps for subscription-free offline navigation. Examine your intended route in detail before treating community-mapped trails as usable access.
No — not a downloadable offline navigation-map app
Maker
Windyty, SE
Windy.com visualizes weather models, radar, satellite imagery, and forecast layers. Treat it as a planning companion to an offline navigation app, not as your primary backcountry map.
Wind, precipitation, temperature, cloud, and snow layers support trip planning. Multiple forecast models let you examine more than one projection.
Before departure
Compare wind, rain, and temperature forecasts for the places you plan to visit. Radar and satellite views provide additional context while you have connectivity.
Trade-offs
Fresh forecast and radar data require connectivity. Model detail does not guarantee accurate conditions on a particular ridge or in a narrow valley.
Who should choose it
Choose Windy to supplement route planning with weather assessment. Recheck forecasts before departure and carry a plan for deteriorating conditions.

No — messaging app, not an offline mapping app
Maker
Garmin International
Garmin Messenger is a communication companion for compatible Garmin inReach satellite devices. It earns a place here for remote-trip messaging and SOS support, not for trail navigation.
Where it fits
Remote-trip communication
Check-ins
Satellite SOS support
Pros
Companion interface for inReach messaging
Interactive SOS with compatible hardware
Internet, cellular, and satellite switching
Cons
Satellite use requires separate hardware and subscription
The app supports direct and group messaging. With compatible hardware, it can switch between internet, cellular, and satellite connections.
Remote-trip role
Pairing with a compatible inReach communicator enables messaging beyond cellular coverage. Interactive SOS requires compatible hardware and an active satellite subscription.
Trade-offs
Installing the app alone does not create satellite connectivity. Photo and voice messaging also depend on the specific paired device.
Who should choose it
Choose Messenger if your safety plan includes a compatible inReach communicator. Test pairing and messaging and confirm the subscription before departure.

National Park Service
The official NPS App combines park maps, visitor information, and downloadable content for US National Park System sites. It is a valuable park-specific companion alongside a dedicated backpacking navigation tool.
The app includes interactive maps, amenities, fees, operating hours, and self-guided tours. News and alerts add useful planning context when connected.
Offline visits
Download the park before arriving somewhere without service. Saved content makes maps and visitor information accessible during the visit.
Trade-offs
Its scope is the US National Park System rather than worldwide backpacking. Saved material cannot tell you about changes published after your last update.
Who should choose it
Choose the NPS App for itineraries inside US national parks. Confirm permits and current restrictions with the park before relying on saved information.

How we picked
Ranked by Cal Brennan, Senior Gear Editor
We started with a long list of backpacking apps that people actually buy, cut anything that could not clear our baseline for durability and field performance, then ranked the 10 that were left against the same criteria. Rankings are editorial. No brand pays for placement, and affiliate links never move a pick up or down.
Load carriage
How the suspension handles the loads the pack is actually rated for, over long days.
Real-world durability
How the material, stitching, or steel holds up after a season of hard use — not how it looks new.
Performance in bad conditions
Wind, rain, cold, and grit are the test. Anything that only works on a nice day gets marked down.
Weight and packability
Every ounce has to earn its place in the pack, but not at the cost of something that fails in the field.
Ease of use
Setup, adjustment, and maintenance with cold hands, in the dark, without the manual.
Value at its price point
Compared against the closest competitors in the same tier, not against cheaper gear in a different class.
How often we recheck this: Reviewed on a rolling basis and rechecked at least once a year, or sooner if a pick is discontinued, revised, or beaten by something new.
Best backpacking apps for a specific job
Skip the ranking — jump to the pick that matches how you actually use it.
Our editors test the gear, pick the ten, and set the order the day a list publishes. After that, the ranking is live: every member star rating feeds the community order, so picks climb or slide as real owners report back. Editorial judgment decides what earns a spot — you help decide where it sits.
Editors set the field
Hands-on testing and spec research choose the ten and the published order.
Readers re-rank it
Your 1–5 star ratings drive the community order on every list.
Rankings keep moving
Picks rise or fall over time — nothing is frozen at launch day.
Award picks
The ranking above is price-blind and judged on merit. These awards call out the pick we'd hand a specific person with a specific need.
Gaia GPS is the all-round mapping pick, CalTopo excels at terrain planning, and FarOut is ideal for supported long-distance trails. Download and test everything before departure, and carry independent navigation and an appropriate emergency plan.
How to choose backpacking apps
Every pick on this page was judged against the same criteria. If you want the short answer, Gaia GPS by Trailbehind, INC. is the one we point most people at. If you want to decide for yourself, here is what actually separates a good backpacking app from an expensive one.

Match the pick to your use
The right backpacking apps depends on what you are actually doing with it: General backpacking; Route planning; Public-land trips; Off-trail planning; Group trip planning; Terrain assessment. Start from the use case, then work down the ranking until you hit the first pick that covers it.
Common mistakes
Buying the lightest backpacking apps you can find and discovering it cannot take a season of hard use.
Paying for a specialist feature you will use once a year instead of the versatile option.
Comparing headline specs across tiers instead of within the same class.
Skipping fit, sizing, or adjustment checks that decide whether you actually carry it.
