The next best thing to having a Google Maps app on your iOS device.
Following what's now known as Mapplegate with Apple's heavily scrutinized Maps App introduced by iOS 6, a developer has created his own maps app predominately based off Google's renowned maps service.
Katsumi Kishikawa has developed a simplistic and straightforward app called Classicmaps, which replaces Apple Maps with a design striking a similar resemblance to the now-removed Google Maps app.
While it doesn't offer notable features such as public transport directions, navigation and Street View, the app is the closest resolution to having a Google Maps app on your iDevice. Or you can settle for the more complete iOS web Google Maps app.
As for Apple's own maps app, it has since shown signs of improvements following an apology letter from CEO Tim Cook.

Although there normally is a bit too much focus and fuss on every tiny thing to do with Apple, when the CEO of Apple comes out and apologizes about a poorly functioning app, then an alternative to said app (which incidentally uses resources from a controversially discontinued and better performing app) is more newsworthy than at least half the other Apple news around.
So don't read Apple articles
IMO, every article here is posted so anyone can see/read/comment it.
You like reading little app-related articles, but don't like the comments? Simple: don't read the comments.
