Thanks for sharing the OSMand recommendation and configuration.
I’ve got a hike coming up, so I just installed it - wow, it’s fantastic. It captures the elevation change and distance. I thought I’d need to limp along with Google maps, but OSMand is sooo much better (and open source).
edit: a word
If you’re whitewater kayaking, it’s not uncommon to have a knife accessible from your PFD.
It can be used to cut any ropes you might be tangled in or (worse case) cut the PFD.
In general, having a knife with you is useful in most emergency situations (and a throw rope, pin kit, plus knowledge of how to use them).
