About

Nuvex takes your app screens and a sentence about what the app does, and returns a finished set of App Store and Google Play screenshots — background, palette, type, headline and layout decided per app.

There is no template underneath. Every set is composed from scratch, which is why the three example sets look nothing like each other.

Two models do two different jobs. The first reads your screens and your description and writes a creative brief for the set — the palette, the type system, what each frame should argue, and the headline for each one. The second paints the frames from that brief.

The part that matters most is what neither of them is allowed to touch. Before anything is generated, your uploaded screen is placed on the canvas and masked. The mask marks that rectangle as off limits, so the image model paints the background, the headline, the decoration and the iPhone bezel around it — and cannot alter a single pixel inside it.

That is why your real button labels, your real data and your real fonts survive into the finished screenshot. Ask a general-purpose AI image tool for “an App Store screenshot of my app” and it will invent a plausible interface that is not yours, with garbled text and features you never built. Apple rejects listings for that. Nuvex avoids it structurally rather than by asking the model nicely.

A five-frame set takes about thirty seconds. Frames render in parallel, roughly 8 to 14 seconds each, and any frame that fails is refunded automatically — you are charged only for what actually gets painted.

Downloads are 1320 × 2868 pixels, which satisfies Apple’s 6.9-inch iPhone requirement — the slot App Store Connect asks for first. The same files are accepted for the 6.5-inch and 6.7-inch slots, so one generation covers every modern iPhone size, and they clear Google Play’s requirements too.

Nothing is locked after generating. Any single frame can be regenerated or revised in plain language while the other frames stay exactly as they are.

Most screenshot tools are template libraries: pick a layout, drop your screens into labelled slots, ship. It works, and the result is recognisable — which is the problem. Anyone scrolling the store has seen that exact layout on four other apps this week.

The alternative was five hundred dollars and a week of a freelancer's time. Nuvex exists for the gap in between: the app is finished, the listing is not, and there is neither budget nor a designer.

• Invent social proofNuvex never puts fake star ratings, award badges, press logos or download counts on a frame. If you did not earn it, it does not go in the screenshot.
• Reuse your design on someone elseCompositions are generated per app and never recycled between users.
• Keep your source screenshotsUploads travel with the generation request and are discarded after it finishes. Only the output is stored, on your account.
• Expire what you boughtCredit-pack credits never expire, and paid downloads stay unwatermarked whatever happens to your plan later.
• Pretend to do videoNuvex makes still frames. App Preview videos need a different tool, and we will say so rather than sell you a workaround.
