The Nokia Here app on iOS is reminiscent of the Nokia maps I used on my N95. Not as polished as the current maps app on the Lumia or Symbian Belle devices.
The map data however is much better (for India anyway) than that of the iOS 6 Maps app, so that is a small plus.
Apple’s iOS 6 Maps app has received so many complaints and been the butt of so many jokes that you’d think Nokia could capitalize on Cupertino’s fail by releasing a stunning maps app to dominate the iOS space. No such luck. Nokia’s Here Maps is a mess.
