You can make a map of your trackings meaning having nearly a year of where you went to all around the world on one map... isnt that special.
you can also share the map with us if you dont bother

thats where you get the tool to extract the data

(actually i dont know if this is only american iphones since some suspect that this was ordered to apple by the us goverment)...
