    The App we've been searching for over 2 years!

    I have been looking for an app like this for over 2 years! Finally, an emergency alert app that gives persistent notifications, and can work with iOS to even alert you when you have Do Not Disturb enabled. Since this app allows a variety of choices for the persistent alert, including a phone call from a consistent phone number, I can set the SIGNL4 phone number as a favorite in my contacts, and then my alert comes through even if I set the phone to DND (and allow favorites in the DND settings). This allows me to sleep without interruption unless there is a true emergency! This app does so much more also, scheduling team members, making sure someone is always on duty, and even making provision for unanswered alerts to be escalated to a manager after a set time frame. We use it at our Church for an emergency. What I really love is that a parishioner calls in to our church phone system and leaves a voicemail in our emergency voicemail box, then my phone emails the voicemail to SIGNL4 app and after the alert, there is the voicemail accessible by a PLAY button within the app! Thank you SIGNL4, you have thought of everything!
