With the rise of the smartphone within the last decade there has been a corresponding rise in navigation apps. As the hardware has become more durable with longer battery life, as well as the growing affordability in solar powered chargers and battery banks, the use of a smartphone as navigation in the field has become much more practical than it has been in the past.

Andrew and Paul use a Smartphone GPS app loaded with USGS 24k quadrangles to navigate a complex off-trail section in the Absaroka-Beartooth Wilderness as part of Backpacking Light’s 2018 Wilderness Adventures Whitetail Trek.

Category Description

For the purposes of this review, I will be looking at apps that can be found on both iOS and Android platforms. There may be some good apps that are excluded because they can only be found through one or the other but for this article, we are taking an ‘all or nothing’ approach.

Many of these apps are free but require a membership or in-app purchase in order to get the most out of the app. The apps being reviewed will include:

  • All Trails
  • Gaia
  • Google Maps Offline
  • Guthooks
  • Outdoor Active
  • Rambler
  • REI – National Parks
  • Spyglass
  • Viewranger
  • Yonder

This list is not comprehensive! New apps are being developed and introduced all the time. In addition, this list doesn’t include some apps that have been around for awhile (like Topo GPS) because I don’t have personal experience with them.

Feature Summary

In this review, I will be looking at what are the most important criteria for a navigation app. These features include:

  • Downloadable Maps
  • GPS Navigation
  • Ability to Import and Export a GPX Track
  • Route and Waypoint Creation
  • Speed and Distance Tracker
  • Altimeter

Criteria for Evaluation

Downloadable Maps

For those who plan on taking a longer hike and might not want the added weight of a battery bank or those who prefer a good old fashioned printable map, this feature is key. Being able to plan a route in the comfort of your home office and then transfer it to your phone or print it out gives more options for how to navigate during the trek.

GPS Navigation

With modern cell coverage, it’s hard to find places without coverage within 50 miles of a freeway or 100 miles of a town. Even so, many of the canyons we get into or the mountains that we climb will not have any signal. This means that an app that uses your phones GPS function is far more useful than one that doesn’t.

The Ability to Import and Export a GPX Track

The GPX file standard has been around since 2004 and has become a vital part of every GPS unit since. GPX records your longitude and latitude in decimal degrees while elevation is recorded in meters or feet. Depending on what you are using GPX to monitor, it may be important to note that times are not recorded in local time but in Coordinated Universal Time (UTC). Simply put, this is the system that allows you to mark waypoints and share them across multiple platforms and devices. This is crucial when marking a point for a group with some members using a dedicated GPS device like the Garmin inReach Mini while others are using an app on their phone and others using printed maps.

Routes and Waypoints

When planning a short hike or a longer trek, using an established trail or bushwacking from point to point, it’s nice to know where you’re going, how you are going to get there and what points of interest are along the way. If you’re venturing into new territory, it’s nice to know where a water source can be found or where a nice camp spot might be. It can also be nice to know what hazards can be found and where they can be found along a given route. This is where routes and waypoints come in. Will an app allow you to mark a waypoint with a detailed description? Can a photo be attached to a waypoint? Will waypoints and routes automatically coordinate or are extra steps needed?

Speed/Distance Tracker

If you are doing any kind of training then this is crucial. For those of us who want a minimal amount of multifunctional gear, a navigation app that can also record speed and distance is vital. This function can also be used to predict how long it will take to get from waypoint to waypoint or how long it should take the fastest or slowest members of your group to get from point to point. A good speed and distance tracker can help you know if you need to pick up the pace or if you can take a few more pictures along the way.


Knowing your elevation can tell you everything from why you can’t seem to catch your breath to how much fuel to bring on a hike. Being able to easily access an accurate altitude reading can be a vital tool in staying safe while summiting a mountain while tracking elevation gain or loss is crucial for performance tracking as well as monitoring for altitude sickness.

All Trails

IMG 0577

AllTrails allows you to record routes then access the statistics and map all in one easy to read screen.  Expanding the map is as easy as a touch!

This app contains hiking, biking and running trails all around the world. All Trails boasts 50,000 trail maps as well as reviews and photos regularly updated by its millions of users. This allows dog lovers, hardcore hikers, mountain bikers, and other users to give local and valuable recommendations for everything from city park walking trails to the Continental Divide Trail and everything in between.

  • With an annual membership, you can download and print customized maps. There is also a real-time satellite weather tracker. Map layer options include topo, terrain, open street maps and more.
  • Without the annual subscription, you can still record and track data during hikes. This allows you to follow the adventurers who inspire you while also saving your favorite trails to challenge yourself. This feature is great for anyone interested in Fastest Known Time or Fastest Personal Time. Lastly, without a membership, your map will still show topo data during your hike.

All Trails is a powerhouse app that integrates trail reviews and beta – a benefit for some users, the added clutter may get in the way of others looking for a cleaner navigation experience. Although the interface is not as elegant as Gaia, All Trails is a strong competitor in this market and has all of the features required for a positive navigation experience. It earns our Recommended Review Rating (read more about our ratings here).


IMG 0576

One particularly nice feature of Gaia is the ability to assign pictures as waypoints. This allowed my Brother-in-law to follow the route that I took and use a better camera to take higher quality pictures.

Gaia has been showcased in several publications including the New York Times and Outside Magazine. This app is designed to give hunters, hikers, offroaders, backcountry skiers, mountain bikers and professional guides a one-stop solution to their mapping needs.

  • At the free membership level a user can research a worldwide catalog of maps but downloading for offline use is unavailable. You do still have the option of tracking vital stats such as speed, distance and, elevation and you can also record trips, add waypoints with notes and photos and share them across devices with friends and group members.
  • At the “Member” level you gain access to downloadable maps including topo, road, and satellite map layers. You also keep all of the vital features of the free membership that make this app so practical in the backcountry.
  • By upgrading the “Premium” membership you gain access to the following additional map sources for download:
    • National Geographic Trails Illustrated
    • US Hunting Maps
    • IGN European Maps
    • Neotreks Premium Land Use Maps
    • Land Management, Elevation Shading, and Slope Analysis Overlays

Gaia’s feature set, highly customizable display, powerful interface, frequent app updates, map layers, ease of use, and outstanding desktop/tablet trip planning features earns this app our Highly Recommended Review Rating (read more about our ratings here).

Google Maps Offline

All the familiarity of one of the most widely recognized mapping tools around the world. Although much can be said for this app, in the context of a navigation app for hikers the big draw is being able to record directions to a trailhead and even take a detailed photo of the area around a destination.

This app doesn’t support waypoints or any of the tracking functions of the other GPS apps on this list.

Guthook Guides: Hike Offline

IMG 0632

Guthook’s app shows its elevation profiles complete with waypoints, which makes planning and navigating easier.

A great app for set trails, Guthook allows you to find waypoints including camping spots, water sources, and great data for the towns that you’ll pass through on longer hikes. Users are able to update current conditions on any of these waypoints but are unable to set waypoints of their own. The elevation profile can tell you where you are along a trail and the distance to the nearest waypoint. Unfortunately, it doesn’t allow you to track your personal data. Importing and exporting GPX are also unavailable.

Map My Hike

IMG 0637

MapMyHike’s primary screen demonstrate that it’s niche market is the fitness market, showing important workout statistics but no navigation tools.

More of a fitness tracker than a Navigation App, Map My Hike is developed by Under Armor and will give you all the data you need to optimize your performance including community challenges to help you stay motivated. It can be connected to other apps and wearables including the various Garmin and Fitbit models.

Outdoor Active

IMG 0578

Outdoor Active’s ability to plan out a route on a desktop then seamlessly access it on your phone makes it especially nice.

Outdoor Active is designed specifically for hiking, cycling, and mountaineering. This app allows a user to plan out trips of any kind using the desktop site or the app independently or in unison. This makes sharing with friends one of the easiest parts of the planning process. In addition to the tracking and mapping features that we expect in a navigation app there are also some considerate safety features. These include an emergency call option as well as up to date weather conditions.


IMG 0645

Because of the social media lean to Ramblr exploring routes from around the world is only a fingertip away.

Rambler is designed with sharing trips across social media in mind. It allows you to plan trips, track all of your vital statistics. You can also plot waypoints and attach photos as well as videos. You can also download maps based on Apple and Google map data for offline use. All of this is integrated with Facebook and Twitter to seamlessly and effortlessly share your treks across a wide range of groups and friends.

REI – National Parks

IMG 0649

Using the same program as HikingProject, each National Park has trails and destination gems that can be sorted by activity, and difficulty.

This app contains complete trail data for many of the most popular National Parks. You can search for hikes in each park using a map display. Each park also has a “best of” list to search for hikes. Hikes can be sorted by difficulty rating, star rating, or elevation profiles. There is also community input giving insights into camping, guided tours, and best seasons to go.

REI – National Parks also comes with a real-time GPS tracker that includes an elevation profile on a terrain or satellite map. In the case of an emergency, you can also send your coordinates to rescuers.

If you want a printable map, the app can link you to where they have a small selection to choose from.


Spyglass App

Spyglass functions as a hi-tech compass that includes a sun/moon/star finder, rangefinder, sextant, inclinometer, and angular calculator in addition to the expected GPS tracker, speedometer, altimeter, and waypoint tracker.

All of the operations work in 3D with augmented reality. This allows you to track stars on a cloudy night or overlay directions and info over the camera or a printed map.


IMG 0652

The overall interface is a step below its competitors – I would describe the map and elevation profile as clunky – but in the overview tab industry standard statistics are presented in an easy to interpret way.

Viewranger gives you the option of downloading maps for offline use but it uses a credit system per map or you can download bundles for a higher price. With that little caveat, you can browse maps and routes posted by some pretty credible sources such as the trekkers at Backpacker Magazine.

Like many of the other navigation apps, you can track location (which can be shared privately in real time with select friends), speed, and distance. What sets this app apart from the others is the ability to use your phone’s camera to show peak names, trails, and waypoints with the Skyview function.

Product Performance Considerations


One of the key features to consider with a navigation app is planning. The two key features for planning are the ability to import/export GPX and download maps for offline use. If you can’t plot points at home to be used in the field in offline mode then maybe you can download someone else’s route and piggyback off of their adventure. If an app won’t let you do either then it probably isn’t worth much as a navigation app.

Import/Export GPX

Alltrails, Gaia, Outdoor Active, Ramblr and Viewfinder do well in this category. Outdoor Active unfortunately has a tendency to crash when adding a photo waypoint while recording a route. Google Maps Offline has the ability to download maps for offline use but they are meant for street-level views not trail level use.

On the export end of things, it is nice to keep a record of where you’ve been for personal records or to show your friends how cool you are. Alltrails, Gaia, Outdoor Active, Rambler and Viewfinder are strong in this category as well, although they all require you to purchase an upgraded membership or pay per download.

Downloadable Map

In one way or another, all of these apps give you the chance to download maps. The feature works especially well with All Trails and Gaia who allow you to plot a trail with waypoints on your desktop and easily move them to your phone. Guthook also does well with an easily downloadable map but doesn’t give you the option of adding your own waypoints.


It’s easy to say that you’ve been there and done that but it’s entirely different to have accurate statistics to back up your claims. It’s also nice to be able to track performance and improvement or to know that the next waterhole, campsite or summit is a specific distance away. For this, you need to accurately know your position along a route to track your speed and elevation along with distance traveled and distance to the next point.


Almost all of the apps do well in this category or they don’t track this data at all. I was able to communicate with the developers at Guthook and they are working to integrate a speed tracker in future updates.


A tricky point is whether or not an app actually tracks your elevation or just gives an elevation profile of your route. In general, if an app will track your elevation then it will also give you an elevation profile. Conversely, just because an app gives an elevation profile doesn’t mean that your ascent or descent has been tracked. Anyone with basic math skills can work around this but for those who don’t want to do the math at the end of a long day the tracking feature is important.

Commentary and Recommendations

Gaia’s feature set, highly customizable display, powerful interface, frequent app updates, map layers, ease of use, and outstanding desktop/tablet trip planning features earns this app our Highly Recommended Review Rating.

If you’re looking for a good all-around app for navigation purposes then All Trails and Gaia are the two to choose from. They both have easy to navigate planning and tracking features and are easy to share across platforms and devices. Gaia has an especially customizable readout that will allow you to see the information that is most important to you and not worry about the other stuff.

Gaia’s feature set, highly customizable display, powerful interface, frequent app updates, map layers, ease of use, and outstanding desktop/tablet trip planning features earns this app our Highly Recommended Review Rating.

If you are looking to do something more specific like a National Park or the Continental Divide Trail then you may want to go with Guthook or REI National Parks. Guthook is especially nice for hikers who are shy on experience in the backcountry and may need the frequently updated information that Guthook provides.

For those that are more interested in using an established social media site to share your exploits then Ramblr is for you. It has all of the tracking features with an emphasis on syncing with your social media accounts.

If you’re most interested in fitness and tracking health improvements, Map My Hike is made by Under Armour and will sync with everything from your GPS enabled shoes to your watch while Viewranger will sync with your phones health tracker app.
