You can ask Android "what is this phone doing?" and it will classify your recent movements as:

inVehicle	The device is in a vehicle, such as a car.
onBicycle	The device is on a bicycle.
onFoot	The device is on a user who is walking or running.
running	The device is on a user who is running.
still	The device is still (not moving).
tilting	The device angle relative to gravity changed significantly.
unknown	Unable to detect the current activity.
walking	The device is on a user who is walking.

I have location history enabled on my phone, and it's been telling Google my location and activity classification more or less continuously since 2012-09-20. This is now included in Google Takeout, so we can map it. What do I tend to do where?

Colors are:

inVehicle	red
onBicycle	pink
onFoot	purple
still	blue
tilting	green
unknown	yellow
exitingVehicle	orange

You can see roads, because they're red (inVehicle), and home/work have a lot of blue (still), but overall this doesn't seem super useful. Maybe there would be something more interesting if I weighted by frequency? (Where do I tilt the most?)
