Nuvex vs Previewed.

Previewed is a scene-based preview builder — pick a scene, drop in your app. Nuvex composes the full screenshot with AI. Different tools for different jobs. When to pick each.

Last updated June 2026

The short version

Previewed is a scene/preset builder — you choose a curated scene (phone on a desk, phone beside a plant, phone mid-air) and drop your app screen into it. Strong for social media and marketing imagery. Moderate for App Store submissions.

Nuvex is purpose-built for App Store and Google Play submissions. It generates the full design (headline, palette, composition, typography) for each frame and exports every required store dimension.

Many teams use both: Previewed for social imagery, Nuvex for App Store assets.
