It was in the first verison of IRIS it had an App lock that required you to put your pin code it. It should be in this version now. If someone leave their phone unlocked that person could access the IRIS app. It should be code to have an option if the user wants to lock app or leave it unlock. Should be a user choice.
You're trying to push 24 hours monitoring Pro service but yet you do not have a lock on the app there was in the first version.
