Activity time recording based on GPS data

With the data from always-on GPS devices (smartphones, in-car devices, etc) it should be possible to identify regular journeys relatively easily. A useful service based on the analysis of this data would be a monthly report on your journeys: frequency; mean journey time; median journey time; maximum journey time; minimum journey time.

It should also be possible to identify location-based activities. For example, going to the gym, going to a paritcular shop, going to work, etc. The equivalent report would include: frequency; mean time spent; median time spent; maximum time spent; minimum time spent; etc.
