User reviews
it's a good app try it
"Funny..." No, not really: I had to test it when no one was around; so, nobody would call it "a false alarm," lol!
Perfect app. I wanted an app that sends sos signals that can distract my child and this app did just that
Damn! Amazing, I'm impressed. You can choose to change the interval and personalize the signal you want to send. Also, you can turn on/off the volume. I like that when it's on, it's completely independent from phone's volume, so it'll always work. Thank you!
