Apps for tracking location while hiking?

Google My Tracks is the best I've found. Shows distance, altitude change, etc. Shows your hike path over Google Maps. Saves hikes to your Google Drive account for access via Maps anytime. Love it.

Yeah, just make sure not much else is running. Tracks doesn't take up too much battery, even though it is using GPS. I think it uses about 5 to 8 percent per hour, maybe less.

Here's a screenshot of the details and a partial of the elevation chart from a hike in the Smokies.

Click this link to see a hike I did last fall. Click the last entry on the left to see the detail summary as shown above.

 

I've kept both distance and time intervals at default. I'm not sure I fully understand the options, but I think it means the distance between data points. So if you set it to a longer distance or more time, your trace will be courser. If you hike for an hour with 15 minutes between points, your track will look like a box (4 points) instead of a true track. I'm not sure though, I've never changed them.

 

I have seen an app called Backcountry Navigator Pro that looks like it would be good for this, and more topo map friendly, but haven't bought it or tried it yet.
