Schools switching to CrisisGo App for Emergencies

Schools in Zeeland Michigan have decided to switch to crisis app that helps facilitate communication in times of crisis such as school shooters, natural disaster, and other threats. I personally think this is a great idea as consolidating information quickly in times of crisis can only increase chances of resolving the situation at hand. I can not think of any downsides but what do you guys think? Are there potentially negative consequences from using apps like CrisisGo?
