More Motorola phones now support Motorola Alert
The free app also will arrange to have your latest location sent out to specific contacts periodically. If you have children that you're concerned about, this is a great app to use to make sure they arrive safely at school every day. And you will also know when they leave school, allowing you to figure out what time they should be arriving home. Once it is set up, the kids don't have to do anything for you to receive the alerts.
Motorola Alert was originally available for the entry-level Motorola Moto E, and the Motorola Moto G LTE. There is no word on whether any other Motorola models, like the DROID series for example, will be allowed to eventually use Motorola Alert.
