We had the big launch a week ago, now we have the apps. Or at least, we have the iOS apps for Nokia Here, should you have iOS 4.3 or above.We outlined all the features of the main program last week, but it's worth going over the app, as it does differ slightly to the web-based software. Not hugely though.Download the app and you get a choice of map views for 200 countries, plus live traffic view, public transport line view or satellite view. You can also save map areas for the times when you don't have network coverage. Useful, to say the least. In 'selected' countries, you can also access community maps created and updated by users, but everyone gets the option to search their history, share places with a tap, organise places you favour into collections and sync those collections with other devices.You also get step-by-step voice navigation, walk navigation through pedestrian routes, parks and so on plus public transportation and driving directions. Talking of directions, all of that data is provided by Navteq, the folk behind numerous GPS systems.It's free to use and download, with Nokia no doubt looking at getting ahead of the game before Google returns to the iPhone and iPad with Google Maps and Apple makes good its own mapping software. Saying that, initial feedback via iTunes isn't great, although there are only three reviews are in so far. But as it is free, you can make your own mind up by grabbing a copy now. If it doesn't do it for you, just delete it.
