What, in addition to an Android device with GPS, would I need to track fitness effort?
I am thinking of perhaps something like a Fitbit, or can the Android do the same?
Also probably a hearth rate monitor.
I have had a Polar monitors in the past, but I think the way it worked didn't really fit my purpose.
What I want to track is to a great extent daily activities like walking and biking, and fitness activities like Pilates or dancing, which are not primarily aerobic.
One activity is longer walks/hikes, it is also a goal to to even harder ones well.
