CritterMap Backcountry Navigator for Android

user rating: 5 of 5 (2 reviews)

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.

Reasons to Buy

  • Full function navigation program without buying a separate handheld GPS unit
  • High-resolution maps available (especially AccuTerra)
  • Add waypoints as you hike, add notes, comments
  • Works on a wide variety of Android phones
  • Active developer who responds quickly to issues and continually evolves the capabilities
  • Fast satellite location, satellite view

Reasons to Avoid

  • No version for Apple IOS
  • If used continually, will quickly suck down phone battery
  • Many capabilities are buried in the menu structure
  • Map management is somewhat kludgy

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 is by no means perfect, nor does it have as much raw capability as the best dedicated Nav devices.  But for the dayhiker, the dogwalker, and the casual weekend backpacker, it might be exactly what you need. The Backcountry Navigator program is cheap, and effective.  It is available through the Google Play store, or at the Amazon app store.  There's a free trial version, but the full version is about $10 at https://play.google.com/store/search?q=backcountry+navigator  Various map sources are available free, and there are also premium map sources available for an extra fee.  I've been using the...

Survival Guide by Max Soderstrom

user rating: 5 of 5 (1 review)

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.

Reasons to Buy

  • FREE
  • Thorough
  • Pictures

Reasons to Avoid

  • Ads

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 app is thorough in explaining basic survival skills that can be very beneficial to someone in a life threatening situation.  I love that there are apps with this kind of information. Since I will have my iPhone with me on most any outdoor trip I go on, I will always have this information with me, without the extra bulk of a book.

High Country Apps Colorado Rocky Mountain Wildflowers

user rating: 4.5 of 5 (1 review)

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.

Reasons to Buy

  • Nearly comprehensive coverage of species in the target region
  • Searchable by common and scientific species and family names
  • Random access searching by a broad range of characteristics
  • Multiple color photos of each species
  • Text descriptions, range maps, and additional info
  • Price

Reasons to Avoid

  • Could combine family and characteristics searches
  • Text descriptions are rather technical for the layman

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 how darn many plants there are out there to ID, this can be a more or less challenging task. High summer in the Rocky Mountains, with its vibrant show of forest, meadow, and the alpine wildflowers, is a prime time and place for me to practice that craft.

Peak Scanner

user rating: 5 of 5 (1 review)

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.

Reasons to Buy

  • Simple to use — just point!
  • Inexpensive
  • Seems to work worldwide

Reasons to Avoid

  • Need a phone with you

Peak Scanner is an app available for the iPhone 4 and above that automatically tells you information about any mountain peak in the distance if you simply point your phone at it. It uses a thing called Augmented Reality, which means (I think!) it overlays extra information on top of the camera view you see on the screen. There are no buttons to press. It just does it's job and very effectively too. And it's very cheap to buy. There is an iPhone version and also one for Android I believe. There are other apps I've downloaded of this type, but they've all been pretty rubbish when there are lots of mountains around - too much cluttered information on the screen.

Top Outdoor App / Map

Gaia GPS Hiking, Offroad Maps App

user rating: 4 of 5 (3 reviews)

The main takeaway for me was that planning a route was significantly faster and more intuitive than any other mapping app I’ve used. The app does all the things we’ve come to expect from mapping apps, including pinning waypoints, creating routes, and tracking hikes, but offers many features that others don’t, including the national parks maps from National Geographic and cell phone coverage maps. The interface is clean and easy to understand and the maps are sharp without clutter.

Reasons to Buy

  • Clear and legible maps
  • Multiple map layers to choose from
  • National Geographic National Parks maps
  • Ease in route planning

Reasons to Avoid

  • It costs money for the best features

Gaia GPS is a map application that allows you to plan routes, navigate on the trail, record waypoints and tracking. With a paid subscription, you can get access to different maps and map layers that can be downloaded for offline use. It can be used with mobile devices (Apple or Android) or the Gaia GPS website. Author at the start of the Glacier Point hike in Yosemite By now, many people are familiar with the basics about GPS apps, but in case this is new to you, your smart phone has powerful navigating capabilities when the built-in GPS function is used with a navigation application such as Gaia GPS.

Knots Guide App

user rating: 4 of 5 (1 review)

When you don't have a lot to do or want to learn a new knot, use this app.

Reasons to Buy

  • Easy to navigate
  • Useful AND interesting obscure knots
  • Some step-by-step instructions
  • Knots organized by type
  • History of many knots included
  • Works when you have ZERO bars
  • FREE!!!!!

Reasons to Avoid

  • Some pictures are better than others
  • A few knots I think of are not listed

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 practice right? Ok, so I'm a nerd. This app categorizes knots into Bend knots, Binding knots, Climbing knots, Decorative knots, Fishing knots, hitch knots, Looping knots, Running knots, Stopper knots and Whipping knots.
