GO Contacts Ex is the latest version of GO Contacts. We have made some improvements to the app, and the UI has been redesigned. The app is now more intuitive and easier to use. We have added a quick-find function that allows you to find contacts by typing the name of the person or the company that they work for. If you are looking to make a quick call or send a message to someone, you can do so with just a few keystrokes. You can now also send an email or batch SMS to a group of people with just one click.
