I got tired of App Store Connect rejecting my App Preview videos, so I built a tool to fix it
I'm an iOS dev. Every time I ship a new app, I hit the same wall: uploading the App Preview video to App Store Connect. A plain iOS screen recording never matches Apple's required specs — so it gets rejected, and I'm stuck opening Final Cut Pro or Canvas just to re-encode a video I already have.
After doing this manually one too many times, I built PreviewASO Screen (previewasoscreen.com): upload any video, trim it to 15–30s in a phone-frame preview, and export it already in Apple's exact format — for iPhone, iPad, Mac, Apple TV, and even the 4K Vision Pro spec (which almost nothing else supports).
It's free to try (1 conversion/day, watermarked). Paid credit packs remove the watermark and skip the queue.
Built solo, side project, still early — would love feedback from anyone who's shipped an iOS app and felt this exact pain.
The interesting part isn't converting videos into Apple's required format—it's removing a release bottleneck that every iOS developer eventually hits. I'd keep validating whether developers adopt PreviewASO Screen because it saves editing time, or because it makes App Store submission feel predictable instead of trial and error.
