Recent Outdoor App Reviews


rated 5 of 5 stars A free navigational app for Android smartphones for the PCT, AT, and CDT. Super easy to use. HikerBot is a free smartphone app that can be used on the three main long-distance trails in the U.S.—Pacific Crest Trail (which also includes the JMT), Appalachian Trail, and the Continental Divide Trail. My wife and I used HikerBot on a section hike of the PCT from Echo Lake in Lake Tahoe to Tuolumne Meadows in Yosemite National Park. While we used Half Mile maps for general navigation, HikerBot was… Full review

High Country Apps Colorado Rocky Mountain Wildflowers

rated 4.5 of 5 stars A well thought-out app that pros and beginners alike can use to identify most of the hundreds of species of wildflowers, trees, and shrubs in the central Rocky Mountains and nearby ranges. As a card-carrying botanist (my BSc is in botany) one of my main ways of relating to the natural world is by paying attention to the local flora, wherever and whenever I am. Depending on how far the where is from familiar botanical territory, whether or not the when is at a time when plants are in bloom, and just… Full review

CritterMap Backcountry Navigator for Android

rated 5 of 5 stars Many people are going out and spending hundreds of dollars on a GPS, then at least a hundred more on mapping. I was one of them. This product works excellent for me and it is nice having a larger phone screen. I spend a lot of time out in  the backcountry hiking, quading, dualsport riding, and fly fishing. So I purchased a handheld GPS online, spent $450 with mapping "sale" price. It was a frustrating joke! The program was very difficult to learn, the screen was very small. I ended up selling it… Full review

Gaia GPS App & Offline Topo Maps

rated 5 of 5 stars Gaia offers up-to-date and detailed GPS topo maps for Android or IOS devices. Best of all the maps are downloadable so your phone can be your GPS even when out of cellular range. I had a Garmin eTrex and then a Garmin 450 GPS that I have used the past 12 years. Both devices were well utilized and displayed good accuracy and much usefulness.  I recently bought the Canada Topo Pro maps for my Samsung Note 3 for $9.99. I liked and used that app for the past few months. Having a big 5.7" display to… Full review

Survival Guide by Max Soderstrom

rated 5 of 5 stars This is an excellent educational app on survival skills. I keep this app installed on my iPhone just in case I find myself in a situation where I don't know what to do. It is a must have for those not familiar with the outdoors or just beginning to adventure outdoors and is good for experts as well. This app is an absolute must have if you like being in the outdoors at all. Especially if you are going to venture away from civilization because you never know what might happen. The Survival Guide… Full review

Knots Guide App

rated 4 of 5 stars When you don't have a lot to do or want to learn a new knot, use this app. A great TS reviewer just reviewed a set of cards which teach various knots and I thought, "What about that knot app on our Galaxy phone that we use Precious?  Think anyone would like it?"  So here we are. I downloaded this app mainly as something to mess with while I traveled since I usually have some perlon cord around to play with. I was tired of the other games on my phone. Besides, who couldn't do with some more knot… Full review

Peak Scanner

rated 5 of 5 stars Amazing hiking app. When I'm out hiking I find it difficult to figure out the names of the mountain peaks I can see using a map. Peak Scanner is a mobile app that is really simple to use. All I have to do is start up the app and literally point my phone at the mountain I'm interesting and it tells me all about it. Including how far away it is, its height (especially how much higher it is than where I am now) etc. Really simple to use. Amazing. Peak Scanner is an app available for the iPhone 4 and… Full review

CritterMap Backcountry Navigator for Android

rated 4.5 of 5 stars Topo map GPS navigation program for Android phones. Download maps in advance from various map sources, or custom source and use them in realtime on your phone while you hike. Add points-of-interest, waypoints. Log your actual routes, save and share them. Excellent product with a somewhat non-intuitive user interface, recommended for backcountry hikers. The Backcountry Navigator program for Android has been a really useful tool for me, which is why I thought I'd share my experience with it.  It… Full review
