iPhone Duo · App Store Connect
Your App Store screenshots, ready for iPhone Duo.
Drop in your app's screenshots: DuoShot spots what would block App Store Connect (rejected size, transparency, text under the fold) and exports the 1398×2034 and 2007×2853 Duo sizes as a ZIP.
Outer display, inner display, or both: your choice. Free trial, no card required.
Demo: a closed-screen and an open-screen screenshot are dropped into DuoShot, which imports and checks them, then flags three blocking issues: text under the fold, a size App Store Connect rejects, and a transparent edge.

Screenshot issues can lead to corrections and back-and-forth with Apple, delaying your release by days. DuoShot checks file dimensions and format, flags framing and similarity issues to examine, and helps you review legibility near the fold before submission. It cannot detect every issue: you must confirm that the screenshots accurately show your app in use. DuoShot guarantees neither approval nor a review time; Apple makes the final decision.
AI can help create or resize an image, but it cannot confirm on its own that the screenshots show the real app in use, that the closed and open screens tell the same story, and that text remains legible near the fold. DuoShot prepares the files and flags items to review; a person makes the final content decision.
