I know the founder and CEO of that app, Virgil Vaduva. I'm trying to get him and others to come to Steemit! I use the app and am a strong supporter of the idea even before I knew Virgil. PeaceKeeper was a competing app, but it lost the battle.

It is related to the app too that I'm a residential security expert, and I'm on here to share what I know to improve people's residential and personal security. If you're interested in such topics, please follow me. I'm also a private investigator, but I won't be sharing much about it to not get people into legal trouble.
