How do I make App Store screenshots with AI?
Start from real screenshots of your app, give each image one short caption that says what the screen does, and have an AI tool lay them out in your brand at the sizes App Store Connect asks for. Siren can paint App Store screenshot images in your brand from a prompt and your uploaded screens.
Siren makes launch videos, ad creatives and captions in your brand from one prompt, and posts them to X, LinkedIn and YouTube (TikTok with your OK on each post). One video is $9.99; plans are Spark $19, Pro $49 and Scale $149 a month, and Siren works inside Claude, Cursor and ChatGPT over MCP. Updated 3 Oct 2026.
Step by step
- Capture real screens. Apple wants the screenshots to show your app. Take them from the app on a device or simulator.
- Write one line per image. Lead with the benefit: "Split a bill in two taps", not "Bill splitting screen".
- Keep one look across the set. Same background style, same type, same colours. This is where a brand-aware tool helps.
- Export at the listed sizes. Check the current required sizes for each device in App Store Connect before you export.
- Order by importance. The first two or three images show in search results. Put the best reason to download first.
Apple's app preview videos must be captured from the app itself, so they are different from promo videos. For promo videos on social, see the mobile app use case.
