Is there any iPhone app that snaps a picture when someone opens the phone?

Is there an app that when ever you open it, it snaps a picture (without one knowing) to inform you who's snooping or something like that? I don't care what that app is i just want anything that has this feature.

for iOS btw.
i don't mind if its paid or if its free throw everything you have

No there isn't.

Why don't you just put a passcode on your phone and then you won't have to worry about that?

  • Why can't I see snaps on my iphone from an android snapchat user? My friend has an android my touch and every time he sends me or my girlfriend a video (we both have iphones) we can't see it? We can see his pics but not videos. We're able to see other videos from other android users and his wife who has an android can see his videos but why can't we? Any help would be awesome!
  • Why can't I open my snaps on Snapchat? I just got the update, and now whenever I get a snapchat and it says "press and hold to view" or "tap to load" and I hold down my finger on it or tap it nothing happens! I can send them, but it won't let me open any. I'm very frustrated. Oh, I have an iPhone 4. How can I fix this?
  • Which picture edit app (for the iPhone) do you use to naturally remove any human being? He photobombed himself in my picture? I went to Disneyland yesterday and I can see my friend photobombed himself in my multiple pictures. I still have them on my phone. Does anybody have any recommendations (ideas) for any picture edit app I can use to edit him out? He's standing on the right side of me. (which I can see he ruined the moment for me.) P.S. Yes, I like to take pictures with other cosplayers.
  • My snapchat won't let open snaps? I have an iPhone 4 and when I get a notification either on my lock screen or a banner, I click on it and snapchat opens but there's nothing there. I've tried reinstalling the app but I got the same problem. My friends send me snaps all the time and I never seen them there. Any help?
