Hiking Apps?

what apps, if any, do most people use?

I have mapmyfitness hiking app that I use, its the free version on my android phone. I find it very finicky most of the time. When it try to share it with others it acts up. After the last hike a few weeks ago I tried to share and it wiped out the entire hike.:banghead:

It keeps asking me to upgrade for the usual monthly fees, but I don't see the value.

I'm just curious if anyone else has a better app that they use.
