App Mockup Generator

An app mockup generator — also called a phone mockup generator, device mockup maker, or iPhone mockup creator — helps you place your app screenshots inside realistic device frames and export polished marketing visuals. Unlike store screenshot generators (which export at App Store Connect or Google Play Console dimensions), mockup generators produce visuals for landing pages, ads, press kits, and Product Hunt launches.

Yes. Nakxi works as a free app mockup generator — no credit card required. Browse all device mockup templates, open the drag-and-drop editor, place your screenshots in iPhone or Android frames, and preview the output. Export limits apply on the free plan; upgrading unlocks full resolution exports and advanced workflows.

The best app mockup generator depends on how much customization you need. Nakxi offers current iPhone, Android, and tablet device frames with a full drag-and-drop editor — you can freely reposition elements, apply custom backgrounds, and add captions. It also connects directly to your App Store screenshot workflow, so you can produce both store-compliant screenshots and marketing mockups in the same tool.

Mockuphone and Shots.so offer quick single-image mockups — drag in a screenshot, get a device frame back. Nakxi goes further: multi-frame mockup layouts (multiple devices or scenes in one design), full caption and background editing, Smart Resize for multiple output sizes, and localization for international marketing pages. If you need one quick framed screenshot, Mockuphone works. If you need a full marketing set, Nakxi is built for that.

AppMockUp focuses on generating mockups from individual screenshots with limited layout control. Nakxi lets you build full marketing scenes: multiple devices in one canvas, custom text, brand colors, and backgrounds — then export at any size. You also get access to App Store and Play Store screenshot templates in the same tool.

Yes. Nakxi supports iPhone mockups (iPhone 16 Pro Max and earlier), Android phone mockups (Samsung, Pixel, and generic frames), and tablet mockups. A single design can show your app across multiple device types simultaneously — useful for landing pages and Product Hunt posts.

Use store screenshots for App Store Connect and Google Play Console submissions — these need exact pixel dimensions and must pass Apple and Google's review. Use mockups for everything else: landing pages, social media, ads, press kits, and investor decks. Nakxi supports both from the same project.

Mockup export size depends on the destination: for Retina landing pages export at 2x (typically 2560 × 1440 px or similar), for social ads 1080 × 1080 px (square) or 1080 × 1920 px (story format), for Product Hunt 1270 × 760 px. Nakxi's Smart Resize generates multiple sizes from one design — set the target size and export without rebuilding.

Yes. Within Nakxi you can build mockup marketing assets and then switch to the App Store or Play Store screenshot generator for the actual store submission. Both tools share your design system so branding stays consistent across marketing visuals and store listings.

Yes. If your mockup includes captions or on-screen text, Nakxi's localization workflow lets you create language variants without rebuilding layouts. This is useful for international launch pages and localized ad campaigns — especially where text length changes significantly between languages.
