Looking for a good star gazing map, or instructions on making a Slippery Hitch knot? Then check out this sweet list Casimiro compiled on The Adventure Life featuring 25 iPhone apps for outdoor activities. A few of my favorites:
This one is a must-have for snow bunnies, providing base depth, recent snowfall, links to weather and webcams, and coolest of all, onsite ski reports from other users already on the slopes.
As its name suggests, Surf Report checks all surf conditions, including height, tide, and swell direction, as well as weather updates and a listing of the best beaches near you.
This app is actually a copy of A. Hyatt Verrill’s 1917 guidebook, featuring 154 knots with instructions and illustrations. A trusted, classic guide right on your iPhone.
For astronomy geeks, this app actually shows you the moon as a sphere (not flat), which no less than 1,800 named features, along with the locations of 26 spacecraft. Something I could lose a few hours playing with for sure.
