App to display previous photos as, ghost photos?

Unfortunately, I don't know exactly what to call it "ghost photos". Because I would like to have an app with which I can take photos and which shows the last image with half the transparency so that I can take two almost identical images. I hope you understand what I mean. I've seen something like that on Stop Motion before. For example, back then on Nintendo 3DS and in an app. Can someone help me, please?

Snapseed and then the point double exposure.

Then you can select any other photo and fade it over.
