Google Contacts
Google Contacts is Google's contact management tool that is available in its free email service Gmail, as a standalone service, and as a part of Google's business-oriented suite of web apps Google Apps.
Contacts, called Address Book before OS X Mountain Lion, is a computerized address book included with Apple Inc.'s macOS.
Contacts is a flexible and convenient place to store information for everyone you know. It’s easy to import names, numbers, addresses, and photos from Facebook, LinkedIn, Google, and even Microsoft Exchange. Contacts will automatically keep your friends’ and connections’ information and profile photos up to date. And iCloud updates your contacts on your Mac, iOS devices, and Apple Watch — so when you enter someone’s contact info once, you have it everywhere.
