ComScore’s data suggests though that comparatively few iPhone owners actually take the trouble to use Google’s maps rather than Apple’s - in part because Apple’s maps are the default for any driving directions or map-related search on iOS 6 and above.
According to ComScore, in September 2012 - just ahead of the introduction of Apple Maps - there were a total of 81.1m users of Google Maps, out of a total of 103.6m iPhones and Android phones users. But a year later, its smartphone data says that the total number of Google Maps users is much lower, at 43% of iPhone and Android users - or 58.7m, despite the user base growing to 136.7m.
"For the average user, even if they have the Google Maps app, they don’t use it a lot," said Andrew Lipsman, an analyst at ComScore. "In a narrow window [after the iOS app download became available] I’m sure there was a ton of activity, but only for a short period."
I like Apple’s maps on iPhone better than I liked Google’s old maps. It never occurred to me to download or use a separate maps app from Google after Apple made their own maps app the default. It’s had a few trouble spots, but nothing major for me. Google maps on more than one occasion seriously misdirected me and made me late for meeting friends at bars or restaurants or hotels. Usually only be a few blocks, but enough to make me later than I always am all the time for everything everywhere anyway.
