What are the Best Climbing Apps for a Smart Phone?
My favorite is Offline Topo Maps from Gaia. This app costs $4.99 but is worth it. You download the area where you’ll be traveling while you have an Internet connection; then the maps work out of network. It has a pretty good touch-screen GPS —great for backcountry day climbs, or as a back-up GPS on longer trips. If you travel a lot, the Mountain Project app ($5/year) is nice; again, you download route descriptions and then access the info out of cell range. Outside the U.S., the Converter+ app (free) helps with all sorts of things—I find the currency and metric-to-English conversions most useful. Remember to preserve battery life in the backcountry by shutting off your phone, or at least turn off Wi-Fi, cellular, and data roaming.
