Marquee: Your whole App Store page, made on your Mac

Hi Product Hunt! 👋 I'm Marco, and I make iOS and Mac apps on my own. Every release ended the same way: hours in a design tool cutting screenshots to Apple's exact sizes, a separate tool for the icon, the listing text spread over a spreadsheet, and then clicking through App Store Connect one language and one device at a time. Then Apple refused something I could have caught earlier. So I built the tool I wanted. Marquee is one Mac app for the whole App Store page: Screenshots: real device frames for iPhone, iPad, Mac, Apple Watch, Apple TV and Vision Pro, over 30 layouts, headlines you can style down to a single word, and one phone that runs across two slides the way the App Store shows them. Preview videos: drop in a recording, trim it, choose the poster frame, put it in a device frame. Marquee checks Apple's rules (length, size, sound track) the moment it's in. Icon: one image becomes every size, with a background for transparent logos and a preview on the home screen, in the Dock and on a watch face. Listing and languages: every field counts down against Apple's limits, and translation runs on your Mac with Apple Intelligence. Preflight and upload: a list of everything App Store Connect would refuse, then one Update sends the text, screenshots and videos with your own API key. It's native SwiftUI, a one-time purchase, with no account, analytics or server: your key stays in your Keychain and your projects stay on your Mac. (I also used Marquee to make Marquee's own App Store page.) I'd love your feedback, especially on what slows you down most when you ship an update. I'm here all day to answer questions!
