Comparison

Nuvex vs AppMockUp.

AppMockUp is a classic device-mockup template tool — pick a scene, drop your screen in. Nuvex is an AI composition tool — the full design is generated for your app. Different tools for different points in a project.

Last updated June 2026

The short version

AppMockUp (and similar mockup-template tools) excels at visualizing your app on a device quickly — perfect for slide decks, pitch documents, marketing pages, and social sharing.

Nuvex is purpose-built for App Store submission. It generates listing-grade screenshots with AI-written headlines, custom backgrounds, and exports to every required App Store / Google Play dimension. Not a general-purpose mockup tool.

Many teams use both: AppMockUp for in-deck mockups, Nuvex for actual App Store submissions.

Using both together

A common workflow: use Nuvex for your App Store submission assets, then use AppMockUp to show those finished screenshots on a laptop or tablet in your marketing page and pitch deck. Nuvex generates the designed asset; AppMockUp frames it in context.
