The Best Turn-By-Turn Navigation App for iPhone & Android

I am done ever getting a built-in navigation system in my car again. It's ridiculously priced, including the yearly updates they offer. My phone does a much better job of finding addresses, hands-down. Here is one that comes highly recommended by lifehacker:

Like its iOS version, Waze doesn't disappoint, and its price can't be beat. It had an especially high bar to meet on Android because Android devices usually ship with Google Maps Navigation built-in, and while that would seem like a logical choice for the best turn-by-turn GPS app, Waze offers a wealth of features that Google Maps doesn't.

Waze provides pretty good turn-by-turn directions, with an automated voice that tells you where to go and a very subtle sound effect to let you know when you messed up and the route is being recalculated. At first I was disappointed by how subtle this sound actually was, but after testing many apps I'm just happy it exists.

Although Waze's navigation skills are very serviceable, it really shines with its live traffic and other data provided by other users of the app.

Waze is also the only app we tested that makes it really easy to find a particular location. It can search your address book, Google, and several other places to get you the address you need.
