I’ve been using Superimpose for a couple months now. It’s basically a photo editing app that lets you easily superimpose one image on top of another. Pretty solid if you’re into that kind of thing.
Here’s what you do – you start with a background image, then you can add a foreground image on top. And there’s a bunch of tools for masking out parts of the foreground, adjusting the colors and exposure, and resizing/moving the foreground around. It’s got a lot of features, though it took me a while to figure some of them out.
Look, if you’re into photo editing and collages, you’ll probably like this app. It’s not perfect – the ads can be kinda annoying if you don’t pay – but overall it does the job. Worth checking out.
