The short version
Rotato produces 3D device mockups and animation — excellent for landing pages, launch videos and social. Nuvex produces the flat still frames that go in your store listing. Different jobs, and many teams use both.
What Rotato actually is
Rotato is a 3D mockup and video tool: import your screens, place them on a rotating device, animate the camera, export video or stills. The 3D and motion work is genuinely excellent.
Nuvex, by contrast, is built for one output: you upload your raw app screens and a sentence describing your app, and it returns a finished five-frame store campaign in about thirty seconds. Your uploaded screen is masked before generation, so your real interface passes into the output pixel-for-pixel while the AI designs everything around it.
When Rotato is the better choice
Genuinely — these are the cases where we would tell you to use it.
You need a launch or demo video
Nuvex does not make video at all. For a Product Hunt launch or a landing-page hero, Rotato is the right tool.
You want 3D perspective
App Store screenshots want flat, straight-on framing, so Nuvex deliberately never produces angled 3D devices.
You need motion for social
Animated device shots outperform stills on social, which is a different surface from the store.
When Nuvex is the better choice
You are filling App Store Connect slots
That needs flat frames at exact dimensions with marketing copy — not a 3D render.
You need copywriting and layout
Rotato frames your screen beautifully; it does not write your headline or design the campaign around it.
You want the store-required sizes automatically
Exports land at Apple's 6.9-inch requirement and clear Google Play without manual setup.
Honest caveats about Nuvex
Not competitors in any real sense. Rotato for your video and website, Nuvex for your listing.
Nuvex also makes still frames only — App Preview video needs a different tool, and we would rather say that than sell you a workaround. And it never puts invented star ratings, unearned award badges or fake press logos on a frame.
Frequently asked questions
Can I use 3D mockups as App Store screenshots?
You can, but angled 3D devices generally convert worse than flat framing in store listings, where the screen content needs to be readable at thumbnail size.
Does Nuvex make videos?
No. Nuvex makes still frames only. App Preview video needs a different tool.
