Superimpose X

Superimpose X is the sort of app photo editors use when one image has to be layered cleanly over another. By our assessment, its real strength is compositing: masks, blending, cutouts, and the kind of layer work that lets you build a polished collage or surreal edit instead of a simple filter job. The cost is time and patience, because this is hands-on editing, not a one-swipe preset machine. In practice it means zooming in on edges, adjusting opacity, and nudging pieces until they sit right. Superimpose X belongs closer to serious mobile editing tools than to casual social-photo apps, so it rewards people who already know what they want to combine. It is less friendly for quick fixes, and the whole point is that it does not pretend to be quick.
