With this app you have complete freedom over which parts of the photos you want to keep. You can remove (or re-add) parts of the images with your fingers, like painting. Change the settings of the brush for fine-tuning. With this technique you can create montages, replace backgrounds or combine pictures any possible way you can imagine. You can also create semi-transparent layers of photos.
Multi-layer support to manipulate multiple layers separately, similar to professional desktop photo editing applications. Color-sensitive brush follows the edges automatically when cutting out shapes.
You can also store the cutouts you made, so they can be reused for different montages.
