iPhone App for compass/navigation/gps?

Anyone have recommendations for an app that can be used for bush navigation?

Spyglass looks promising

I use these…

Gaia GPS

Topo Maps

Spyglass looks interesting. I just downloaded it to try it out.

Spyglass claims to have Mil specific navigation info which sounds interesting.

Let me know how they compare.

I’m going on a 3 day backcountry snowshoe into a high altitude cave system coming up and wanted to play with some iPhone Nav apps during the trip.

Thanks for the info!
