Motorola Assist and Motorola Connect are both now found in the Google Play Store
Also being added to the Google Play Store is Motorola Connect. This app lets you see from your Chrome browser who is calling your phone. You can also send and receive texts from the desktop browser as well. You need to install a special extension onto your Chrome browser which you can find by clicking on the sourcelink. It's a time saver when you're working on your desktop.
Both apps are supported on the Motorola Moto X, Motorola DROID Ultra, Motorola DROID Maxx and Motorola DROID Mini.
