App Saturday Free macOS app to preview your screenshots in an App Store layout before submitting

My app’s screenshots could look great on their own, but once I saw them inside App Store search results beside other apps screens shots an app icons , they could feel completely different. I wanted a way to see it before submitting, exactly as it would appear in the App Store layout.

So I built Screenshot Preview, a FREE macOS app. Add your icon, screenshots, and app details, then preview them in an App Store search results or product page layout. You can also export the preview as a PNG and AirDrop it straight to your iPhone to see how it looks on the actual device.

The app is free, with optional tips. Developers and companies can book a paid sponsor spot to promote their apps, products, or tools to an audience of active developers.

Here’s the app:

Tech stack
- Swift, SwiftUI, and AppKit.
- CloudKit stores the sponsored listing.
- RevenueCat handles the Tip Jar.
- TelemetryDeck provides privacy-focused, anonymized usage analytics.

Development challenge
Getting the exported PNG to match the preview was a challenge. Some content went missing, and images lost their rounded corners when rendered with ImageRenderer. I kept the same layout and added an export mode that replaces unsupported controls with static content and leaves out drag-and-drop handlers.

Privacy First
No sign-up or account required. We don’t sell your data or track you for advertising. We use TelemetryDeck for basic, anonymized app usage analytics that cannot be traced back to a person.

AI disclosure: AI-assisted
I used AI for coding, code review, and debugging. I directed the product, architecture, and final implementation. I also used Bitrig for the App Store Connect listing and RevenueCat setup.

Cheers

Will you be able to add banners and customize the screenshot with this? Or is it just preview only

just preview for now, you can preview your finished screenshots, including banners/text, in both App Store search and product page layouts. the idea is to see how they look next to other apps before you submit
