ScreenKit takes the screenshots you already have and turns them into store-ready sets: framed devices, captions, backgrounds, fifteen templates, caption translation into about eighty languages, and exports at the exact sizes each store wants, from iPhone 6.9” to the Play feature graphic.
I built it because I kept doing this by hand for every app I shipped, and because I keep meeting indie developers with no designer. Pick a template, drop in screenshots, write captions, and the export sheet produces every store size in one zip. Text flips to light automatically when a background is dark. A CLI renders the same projects from the terminal, and a Pro upload sends the set straight to a store draft.
The screenshots below show PassFirst being framed inside ScreenKit, one of my apps inside the other.
