Syn-Apps Mobile is a cloud service that allows users to receive critical and non-critical notifications on their mobile devices. When situations occur, recipients receive push notifications with text, images, videos, and/or audio sent from SA-Announce containing important information about the situation. It also facilitates two-way communication between the recipient and the notification's sender. Recipients can acknowledge they received the notification, as well as respond to the sender with text, photo, video, as well as share their current location. Syn-Apps Mobile allows administrators to alert unlimited mobile recipients without the transaction cost of traditional SMS services. Additionally, administrators can customize their Syn-Apps Mobile application with unique branding and user-defined registration fields used to collect pertinent data to effectively target and deliver appropriate notifications to each registered user.
