Screenshots or a preview video: which actually moves your App Store conversion rate? A practical breakdown of where each one wins, and how to use both together.
It is a question we hear constantly from indie developers with limited time: if I can only invest in one, should it be screenshots or a preview video? The honest answer is that they do different jobs, and the highest-converting product pages use them together deliberately.
What screenshots do best
Screenshots are scannable. A viewer can absorb a captioned screenshot in under a second, and they hold up everywhere: search results, share sheets, and the moments when a preview has not loaded or autoplay is disabled. They are also the only visual a viewer controls; people swipe through them at their own pace.
- Best for communicating breadth: five distinct features in five frames.
- Reliable: always visible, no playback required.
- Strong with bold captions that state benefits, not feature names.
What a preview video does best
A preview shows motion, flow, and feel: the things a still cannot. It answers “what is it actually like to use this?” For anything interactive (a gesture, an animation, a real-time result) video is far more persuasive than a static frame trying to imply movement with arrows.
- Best for demonstrating interaction and delight.
- Autoplays at the top of the listing on iPhone, capturing attention first.
- Builds trust: seeing the real app in motion reduces the “is this legit?” hesitation.
Screenshots tell people what your app has. A preview tells them what it feels like. Conversion happens where both land.

How they work together
Think of the preview as the hook and the screenshots as the close. The autoplaying preview earns a few seconds of attention; the screenshots let an interested viewer dig in and confirm the details that pushed them over the line. Keep the message consistent: the promise in your preview’s opening frame should echo in your first screenshot caption.
A simple production workflow
- Record one clean run of your core flow on a modern iPhone.
- Cut it into a 15–20 second preview with tap indicators and text overlays.
- Pull your five strongest still frames from the same recording for screenshots.
- Caption each screenshot with an outcome, matching the preview’s language.
- Export everything at Apple’s required dimensions and upload together.
Because both assets can come from the same recording, the marginal cost of producing a preview alongside your screenshots is small. prevy is built around exactly this flow: one recording in, frames and a clean preview out.
