The One Call Now App is a mobile companion to the on-line mass messaging service. It gives clients access to automated tools that send SMS text, voice, and email messages to any size group, turning your phone, tablet or your computer into a mass-messaging powerhouse. Users can quickly record and send messages to all contacts, or to one or more subgroups. All messages can be stored for re-use as needed. Record the message in your own voice using the app, or use the text-to-speech feature to type a message instead and have it delivered in a natural-sounding automated voice. View message reports on your phone or tablet to see who received the message, no matter where you are. Use the app to send emergency alerts and closings, appointment reminders, employee notifications, event announcements or any other type of message that needs to go to a large group of people quickly. Contacts can even reply to the message via phone, email or text.
