Contactosaurus runs on Windows PCs and manages Google contacts - the contacts that are used in Google applications like Gmail, Android phones, Picassa, Chat, and more...
In geek gibberish, Contactosaurus is a Windows client application that remotely manges your Google contacts via calls to Google API's. API's are methods Google provides so non-Google programs can access Google contacts is a safe and orderly fashion.
Contactosaurus provides a fast, rich, and familiar Windows environment for managing Google contacts. While very functional, the Google contact application is a bit bland and a little cumbersome. Contactasaurus is faster because it only passes Google contact data over your Internet connection. With Google's contact application, your web browser must receive the Google contact data AND all the html in the pages that display your data. More stuff to send over the Internet means slower.
No, but we do have some other fine products (Desktop Sales Office) that will manage contacts on your Windows PC and also share them over the Internet. If you have LOTS of contacts, Desktop Sales Office is a pretty good alternative.
Google manages the entire process of synchronizing Google contacts with Android powered smartphones. Changes you make to your Google contacts with Contactosaurus are automatically distributed to your Andriod powered smartphone by the phone's connection with your Google account. Sweet and simple.
