Contact Maps shows your current location and the locations of the addresses of your contacts in the Contacts app. It will show your all of your contacts, or just those in one of your Contact Groups. This app is an easy way to find out who has an address close to your current location and is ideal for sales people keeping tract of customers and prospective customers, or for those of us who just want to know who lives close by.
You can look at the details of your contact and initiate a phone call or text message from within the app, or seamlessly connect to Maps to plan a route.
