I found GPS Tracks and it seems to do what I want easily. Turn it on and away you go. It tracks movement (which you can play back), altitude, speed, etc. More than I need.
You could use this for a motorcycle ride, a hike, a quick jaunt around the neighborhood. I took a 30 minute test drive and it didn’t seem to eat into my battery too much.
Very handy, very cool, and the $4 saved me a lot of personal development time I was planning on to make the app myself. This easily saved myself a lot of time and effort.
