City Maps 2Go
If you can't afford the $6 for unlimited maps on OffMaps 2 (err... maybe you shouldn't have an iPhone?), City Maps 2Go is yet another option you have, and it's available for the low price of $1.99. With over 7,000 maps currently available, support for all kinds of iPhones and iPads, and the ability to download as many as you want for just $2, this contender makes a worthy case for itself as part of the market. Locations with maps available include places like New York, London, Paris, Berlin, Hong Kong, Beijing, and around 6,994 more. Sounds pretty good, right?
One problem a few customers have complained about is the fact that if you download a map in a poor resolution (meaning the image is pretty far zoomed out), you can't zoom in until you are within range of an Internet access point again. This means that if you forget to get the highest resolution and then require it at a time where it's unavailable, you're pretty stranded!
Still, a comprehensive road atlas of every city in the world for $2? Come on, it doesn't get much better than that.
