Anti Theft Alarm

Can’t set the alarm to go off because it goes off as soon as I set it

I have to admit off the bat that I downloaded this app purely for fun. I have a coworker who likes to use the camera swipe feature of the iPhone to take random photos on people’s phones when they leave their phones unattended on their desks. You’ll later look at your photo roll and find pictures of coworkers. I searched for apps that would sound alarms if the phone was moved and this is the one I chose. I tested it myself a few times to make sure it worked... each time it went off without issue. I trained myself to activate the app every time I stepped away from my desk. A month... maybe two had passed and he hadn’t tried it. One day I leave my phone... come back and go to unlock it and just the small touch of me putting my finger to the fingerprint scanner was enough to sound the alarm. I opened my phone to find that the coworker had successfully been able to take photos on my phone without the alarm sounding. He picked it up... carried it around and took photos of various people and put the phone down on my desk. Nothing happened... until I touched the phone to unlock it. Extremely disappointed with this app.
