Great app, when it works. Sometimes it tracks my wife's travels, sometimes mine. But rarely does it show us both traveling, even when we're traveling together. We just got home from going out for brunch. I got a message from the app saying my wife just completed a 4.5 mile trip. Yet when I opened the app, it said she had been home for three days. Other times, it's shown where she's gone, but says I've been home for several days, when that isn't the case. Great potential, but not reliable app.
