What Apple actually wants to see
The preview should show the app in use — real screens, real interactions — not a marketing sizzle reel of abstract graphics. Apple reviews previews and rejects ones that feel like ads rather than demonstrations. Lead with the core experience in the first few seconds, and keep captions readable since many people watch on mute.
How to make one without an editor
Exporting to exact device resolutions and codecs is the tedious part. Describe your app to Maybe Labs and generate an on-brand preview sized for the store, with captioned on-screen text and clean pacing. For the structure that converts installs, see how to make a product demo video that converts, and for runtime, how long a product video should be.
