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.

When to pick AppMockUp
- You need mockups for a pitch deck, blog post, or marketing site
- You want to show your app on a laptop, tablet, or smartwatch — not just a phone
- You're okay doing the design direction yourself and just need a device frame tool
When to pick Nuvex
- You're preparing App Store Connect or Google Play Console uploads
- You want the full design (headline, background, typography) generated for your app
- You want every required store dimension exported automatically
- You want the 1024×500 Google Play feature graphic as a first-class output
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.
