GPS App For iPhone
iPhones are great at a lot of things, but Android phones have always had superior GPS with turn-by-turn directions. Apple attempted to remedy that with Apple Maps in iOS 6 but everyone knows they laid a big egg on that one. So to get a really good experience you need a third-party GPS app for the iPhone. There are many choices out there and to help everyone out, I recently reviewed the Top 5 GPS Apps For The iPhone.
There are three different types of map apps -- maps provided via mobile broadband; maps on board; and hybrid, where a large region of data is downloaded as needed. Picking the right app depends on your navigation needs, your data plan, and how much free space you have on your device.
I like TomTom for iOS. The app has a decent interface with maps on board, and it offers turn-by-turn, voice-guided navigation. It works on the iPhone or cellular iPad with their built in AGPS receivers or with the iPod Touch when it's connected to a GPS Car Kit. The latest version, which makes use of Facebook Search to help you find local points of interest, is getting mixed reviews in the iOS App Store.
