High Sierra Topix

I have an Android cell phone and I want to download a GPS App. Anyone out there have any suggestions? I'm looking for a user friendly app that doesn't drain your battery. Any help would be greatly appreciated. Thanks, js hill

The conversation is several months old, but have a look here:

There may be better apps out there now.
