Is this an official App Store preview recorder?
No. This page is a screenshot-based draft and storyboard builder. Official App Store previews should use footage captured on device and normally run 15 to 30 seconds.
Can I still change duration and screen order?
Yes. The page starts from an App Store-shaped draft preset, but the normal arrange, pacing, and style controls remain available.
Does export stay local?
Yes. Preview and export remain in the browser, so the screenshots and draft video do not need server-side rendering.
Can I submit this video as my App Store preview?
No. Apple requires app previews to be captured on device, and an assembled sequence of static screenshots is not that. This page exists to draft and review the sequence before someone records the real thing.
What are Apple's App Store preview requirements?
15 to 30 seconds, captured on device, up to three previews per localisation, with the first frame acting as the poster frame. The portrait resolution is 886 x 1920 and the landscape one is 1920 x 886, which are the canvases here.
Why does the tool stop at 15 seconds?
Because the duration options are 6, 10 and 15. That means only the longest option even touches Apple's 15-second floor, and there is no way to storyboard a full 30-second preview in one pass.
So what is the point of a storyboard?
Pacing and order. Recording an app preview is expensive, and most previews fail because they try to show six features in twenty seconds. Playing the sequence as a timed slideshow surfaces that before you book the capture session.
Does the draft video leave my device?
No. Frames are composed on a canvas and encoded in the browser, which matters because pre-launch app screenshots are usually the last thing you want on someone else's server.
