The system is easy to use and has all of the features you need for mass notification. It's great that it can be used with multiple platforms (iOS/Android) so we don't have to rely solely on one platform. I wish there was more information about the status of notifications sent out as well as how many people actually received them. Sometimes we get the impression that our messages aren't getting through but then when checking later they are showing up somewhere! Great product if your looking for something simple and affordable. Using this software allows us to send out alerts to thousands of employees at once without having to hire an expensive service like Twilio or Slack.
