The new Google Maps app is simply amazing, by far the best mobile map app that I’ve used even if you take accuracy off the table. I used it this morning and its vocal driving directions are actually better than Apple’s app. They give more detail in road names and things like that and honestly I think the voice is better and more natural too. If you have an iPhone and haven’t tried it out, you really need to. The Verge has a good write-up about what’s new.
