In early 2008 , google and apple collaborated and ape was using google map tiles for marking in apple maps but in 2009 apple refuse to provide full control and features of google map.
So then apple decide have its own map and in they introduce its own map which was again bring shame to them since , it mispelled some name and locations
EX-parks were labelled as Airport , and misleading directions as well,,,
Even turn by turn was missing but in 2013, with ios 7 apple bring this feature and locating the famous spots and sites in both watch and iphone with acquisition of 5 other companies
Further acquisition with MAPSENSE in ios 10, it help locating gas station, refreshed view , drop pin for parked car ,fast food location.
But ios 11 has been completely competative of google maps since it comes with, inside view of malls, lane guidance ,Augmented reality.
Overall, they both are equally used and in America only there are 23 million user of apple map.,,,and google map has 180 million
Even in America Apple is running apple map car to internal depth of object since 2015. Which has improved and improvised a lot
I have enclose figure for this
thank you
if u have any query
