From Filippo Veronese:
A double front and rear facing camera, works with any iPhone! Include a picture of yourself in the picture you are taking and show everybody what you really are up to! Great as evidence of you being in a specific context! HOW TO USE: 1. Launch the app 2. Drag the user icon picture in picture to your favourite location around the screen 3. Tap on the camera icon. The app will take a first picture of what you are looking at and a second one of yourself automatically after 3 secobds. The second picture is taken with the front facing camera when using an iPhone 4; with any other iPhone model flip the phone to portrait you in the second picture in picture. NOTE: The lite version includes Double Camera's logo in the pictures. To take pictures without the logo download the normal version of Double Camera found in the iTunes App Store.
