Before After Cam is a free Android app that allows you to retake any existing photo from the same perspective. The app is perfect for those who want to recreate a previous moment or update an old photo. All you need to do is select an old photo from your gallery, and the app will show it as a semi-transparent reference on your camera preview. Then, match the reference with your camera preview image, shoot, and let the app assemble a side-by-side view of the "before" and "after" image.

The app features an easy-to-use icon-based user interface that makes it intuitive and efficient. It's a creative way to use your Android camera and share photos with your friends and family. The app also offers a new feature called "Magically Match Image Impression" that is available in the Pro version.
