I do like GPS navigation apps basically as most I have tried gives a better navigation experience so far. I just did my hands on an app Localscope from Cynapse which does the same, but with a different execution.
The app does the same navigation, but the idea is distinctive. The app is well integrated with the Google, Bing, Twitter, Foursquare and finally Wikimapia. On launch the app shows a list where you can find a lot of things to search like Banks, ATM, Cafe, Hospitals etc, etc,. You can find lot more on scrolling down. You are given with options to search with Google, Bing, Foursquare, Twitter or Wikimapia. By default the search result shows by Google and displays the results related to your queries. Just tap on the right result that provides a detailed page with the spot information. You can just scroll the results from Bing or Foursquare or any tweets related to your query using Twitter etc,. Or you can just tap the browse all nearby option that delivers all the spots respective to your search.
By the way you can just delete a particular category if you don't wish to list by just sliding it to the left or right. On tapping the result you will be given a detailed view on the spot like contact numbers, Google map view and a nice option to add the details to the contacts. Apart from that there is sharing options like you can just email, Tweet or share it in your Facebook wall.
There are three types of views available like list view, map view and finally augmented reality. All works pretty fine and I just find the AR awesome as it guides me more realistically. But somewhere I just tested the app on my iPod 4G where I didn't find the AR option.
You can turn the GPS off/on, set your current location and there is a GPS meter and I am not sure what exactly that refers. Simply saying on the first looks I was not much impressed on the app, but once I started digging in, Localscope just delivered the best. Of course, a simple integration of the search, social networking all leads to the purpose of navigation is what Localscope.
Localscope is available on the app store for $1.99
