Outdoor Apps Reviews Part 2 (Snow Safety Apps)

A couple weeks ago I kicked off this seasons weekly gear reviews with Outdoor Apps Review Part 1, where we looked at three of my most used outdoor apps; ViewRanger GPS (USA)MyRadar, and PeakFinder Earth. While those apps covered navigation & weather, for Part 2 of this series I’d like to focus on snow safety apps. Check them out below and if I’m missing a must have app please let me know in the comments below so I can check it out!

  1. Theodolite – $3.99

“Theodolite is a multi-function augmented reality app that combines a compass, GPS, map, photo/movie camera, rangefinder, and two-axis inclinometer into one indispensable app. Theodolite overlays real time information about position, altitude, bearing, range, and inclination on the iPhone’s live camera image, like an electronic viewfinder.” – developer’s website

I use this app mostly in the winter while teaching avalanche courses and ski touring in the back-country. You can look down a slope or gully and get accurate information on aspect, elevation, and angle, three critical components to terrain selection when managing avalanche risk.

Check out this short video showcasing its features.

2. Mammut Safety App Free!

I usually suggest to my students on the first day of an avalanche course to download this free App, finally available on Android as well as iOS. It is packed with functionality but I use it most often for its quick and simple clinometer. Check out the other cool features here (and brush up on your German):

3. ULLR’s Mobile Avalanche Safety Tools $9.99

There are a few different “observation & recording” snow science type apps out there. This is definitely one of my favorite for its comprehensive scope and intuitive design. It is however an advanced app requiring a strong foundation in snow science and avalanche phenomenon to really be utilized. To put it bluntly, if you have never taken a formal avalanche course or had an amazing mentor this app may be a bit too much. Seek qualified instruction!

Ullr's Mobile Avalanche Safety Tools

Automatic graphing of snow pack observations and instant aspect/angle/incline measurements using iPhone’s camera, GPS, and gyro-meter.

So there are three apps to check out for this upcoming winter season. I’ve used them all on an iPhone 5s but will be switching soon to the iPhone 6s Plus, and I’d be lying if I’m not a bit giddy about all that screen space for navigation focused apps. I’ll also be testing a Thule phone case to protect that beauty from the type of abuse I expect it to take. Who knew Thule makes phone cases?

I have some other snow focused apps I’ll mention in Part 3 of this series. In the meantime let me know what apps you rely on in the winter in the comments below!


About David Lottmann

David grew up skiing in the Whites and started climbing at a summer camp just north of Mt. Washington when he was 16. Those first couple of years solidified climbing as a lifetime passion. From 1996-2000 he served in the USMC, and spent the better part of those years traveling the globe (18 countries). After returning to civilian life he moved to North Conway to focus on climbing and was hired in 2004 as a Rock and Ice Instructor. Since then Dave has taken numerous AMGA courses, most recently attaining a Single Pitch Instructor. He has completed a Level 3 AIARE avalanche course, is a Level 2 Course Leader, holds a valid Wilderness First Responder and is a member of Mountain Rescue Service. When David isn't out guiding he enjoys mountain biking, kayaking, hiking, backcountry skiing, trying to cook something new once a week and sampling new micro-brews. He lives in Conway, NH with his wife Michelle, son Alex, and daughter Madalena.

  1. Hi David. Unfortunately Theodolite appears to be iOS only, but for those of us who use Android, Dioptra seems to be a great alternative.
