Four million downloads after launching its HERE mapping app for Android devices back in October, Nokia is today bringing HERE to iOS devices. I’ve been playing with the app for a while leading up to launch, and it’s a true Google Maps and Apple Maps competitor…

One of the highlight features of the HERE app for iOS is saved maps, which allows you to essentially put the entire experience directly on your device for times when you don’t have a data connection. The offline mode will even let you search, get directions, and find your own location. Like similar solutions from other mapping apps, you’ll be able to download cities and countries a la carte for offline mode out of the 150 or so maps available offline.

Other features you’ll find in the HERE app: directions for walking, public transit for 950 cities, and turn-by-turn navigation for vehicles with voice guidance/spoken street names. A lot of real-time data is pulled into the app, and a unique Collections feature keeps track of saved points of interest.

The HERE app for iPhone arrives today on the App Store. More screenshots below:

When you have a data connection, HERE’s “hybrid engine” combines saved maps with online information — such as live traffic (in 40+ countries), real-time public transit (25 cities), and photos and reviews for the places shown on the map… Collections let you save places ahead of time. You can create and view Collections on any HERE app — iOS, Android, Windows, etc. — or on the web at here.com.
