Looking for Stealthy phone camera app

[candaulist]

Had a great one downloaded from the google store a couple years ago. The screen was blank, or of a website, so it looked like you weren't taking pictures. shutter silence, of course, and best of all, you could shake your camera when you needed to take a picture fast, it would wake up the app, and wa la, take the picture.

I've looked lately and the apps are pretty lame, and not anywhere close to the app I just described.

Anyone have any sources for good phone apps for discrete pics?

Thanks
