I love what this app aims to do, great cause. I find the app relatively easy to use. Id offer the developers the following feedback: 1) I cant figure out how to hear and test the auditory alert this app will presumably produce if Im alerted to a response incident. 2) it appears on the home screen I am following Seattle FD by default, but my settings dont show Im following any agency and I cant figure out how Id select an agency to follow.
