I just installed this app today. Recently found a lost Android phone with no pass code. I had to look his contact list to get hold of the owner. When I found one, which says mother, I ended up calling his mother in-law who lives in Lebanon. A long distance call from Canada to Lebanon. Having such an app with passcode would have been very ideal. In any case the owner was happy for getting his lost phone which he rewarded me with $25 Boston Pizza gift card.
