XScreenshotter help you make your screenshot look like one from an iPhone X. The major difference between an iPhone X screenshot and an screenshot from other iPhone models is the bar in the top of your screenshot. All this app does is replacing top bar in your screenshot with a top bar from iPhone X.
Currently we only support in-App screenshots with a white top bar. Other colour will be supported in future updates.
All iPhone models except iPhone X are supported. Deepest apologies for iPhone X users.
