As I promised, I have a follow-up to my original Android outdoor app post from September. Here are a few more useful free apps to help make the most out of your outdoor experience:

MyTracks. Google’s newest version of this GPS tracking app is a winner. Recently updated at the end of September, the app records your treks and stores geographic information as well as speed. It allows users to share treks as GPX, KML, CSV, or a TCX file and will also keep aggregated stats of all your trips to include total distance, time, average and maximum speeds. The updated version has an updated UI for controlling recording, and updated widget for your Home screen.

U.S. Army Survival Guide. Based on the Army’s FM 3-05.70 Field Manual, this app is loaded full of useful intel from Firecraft to Field-Expedient Weapons, Tools, and Equipment, there are 23 chapters and nine appendices. The appendices include the creation of survival kits, identification of poisonous plants, insects, spiders, snakes, lizards and fish as well as how to forecast the weather. Spend $1.99 and get the ad-free version that will allow you to store the app to your SD card and use it offline. I mean, if you’re really in the backcountry, a cell phone tower may not be in reach. That would be $1.99 well-spent.

My Gear Pack. A fairly new app and a hidden gem with only a few hundred downloads, My Gear Pack links with your Google account to help you create an inventory (with pictures) of all your gear and create checklists for future outings from your inventory. You can share your lists with others and also see what others are taking for their outings.

Virginia Tech Tree ID. Nearly one thousand North American trees and plants are included in this versatile dendrology (study of trees and plants) app. There are more than 6,400 color photographs of leaves, flowers, fruit, twig, bark, form, and range maps of each species offered. Quite possibly the most comprehensive identifier available for Android, the VTTID app can narrow down species using your built-in GPS. Virginia Tech recommends downloading the 650 MB database file via WiFi, but it is so worth it. Android users, rejoice in the fact that someone developed your version before the iPhone’s version.

What apps do you have on your Android device for the outdoors?
