Is Google maps show the correct location when you are offline?

Greetings to all, I am very glad and excited to be a member of the RateBeer community. I am a big lover of travel. Whenever I can make me free, I make busy and relax myself by traveling. But sometime some areas do not allow the internet and if allowed it did not access the internet.

So on that time it very important to track the location and I was searching some information online that how to manage that time. During searching, I was found an useful into here that suggested Google maps will work when you are offline.

But I have a question here, this new feature has included in Google maps, how many users benefit using the feature? Is this feature work same for iPhone users?
