ADT Pulse used to be a great app; however, like many other reviewers are saying, it no longer works. I have tried to speak with customer service, but keep getting told there is nothing wrong with the app. Obviously there is or there would not be so many bad reviews. I have always respected ADT as a security company, but seeing that so many people are having issues with this app and the only answer seems to be to call customer service, maybe it is time to switch to another provider.
