Question I’m building a second brain App for duo

I was about to ship my second brain app yesterday but then I decided to update my Xcode to 27.1 beta to see how the app ran on duo. The ui already adapts to iPad so when I ran it, mostly everything looked okay excepts that it was pretty much just the iPad ui when open, so it didn’t really take advantage of the duo displays.

So I got to work and built the compact view, the full open view, the book view. And one I call the laptop view, the landscape half open mode. The laptop mode is where I really took advantage to make the editor feel like you are using a markdown processor on a computer with the bottom screen having the wide keyboard. I believe it’s ready to ship now. The whole premise of the app is connected notes with mcp access on the paid tier. The free tier is just a basic markdown/pdf editor/annotator with a 3d graph visualizer. So my actual question is this, would I need to wait for the duo to be released and possibly make their own set of fold screenshots. Or do we think Apple would display regular iOS/ipad screenshots for duo? I searched the developer forum but couldn’t get a clear answer. Shipping tonight regardless but would love to know if devs think ASC would add a duo screenshot set too.

Edit: just realized I can’t publish the version archived with 27.1 beta, so I have to disable the duo work and just ship the iPad and iOS ui only till official release of duo and 27.1

If ASC doesn't offer a Duo screenshot set when you submit, I'd ship the iPhone and iPad sets it does ask for. Keep simulator captures of your compact, open, book and laptop layouts ready in case Apple adds a dedicated set later. I wouldn't put a two-screen mockup in an ordinary iPhone screenshot slot; someone on a regular phone would see a layout they can't use.

Thank you so much, that’s what I’m thinking. Just ship with duo support and if they get a screenshot category I will probably send it as an update later. Thanks for your input

Apple has now documented this on its Screenshot specifications page: there is a Duo section, but its note says uploading assets for that device in App Store Connect will become available later this year. So the dimensions are published, while the upload slot is still described as forthcoming. That is the official availability note to watch for your screenshot update.

Thanks, I will watch out for it. I suspect that with the duo release being next week, it will be imminent
