Previewed is popular for 3D device rotations and animated video mockups. However, if you need a flexible layer-based design canvas, instant AI-powered layout and copy generation, and dedicated companion utilities (like a Screenshot Beautifier) without watermarks or attribution, AppGrowthKit is the perfect choice.

Previewed (previewed.app) is an online mockup and screenshot generator built to help app developers and designers create professional promotional materials. It is widely recognized for its 3D rendering engine, which allows users to customize the rotation, pitch, yaw, and roll of device frames. Previewed also supports video mockups, letting users wrap app screen recordings inside animated 3D device frames and export them as MP4 or WebM files. The tool offers a free tier requiring Creative Commons attribution, a $9.99 one-time purchase option for basic commercial use, and a $19/month subscription for unlimited high-framerate exports.

AppGrowthKit's built-in AI generators analyze your app's value proposition and build complete screenshot layouts, text overlays, and visual styles in seconds. Previewed requires you to browse fixed templates and manually enter copy for every frame. AppGrowthKit saves you from starting from a blank screen or a generic template grid, getting you to a polished design instantly.
With AppGrowthKit, every frame, text box, graphic, and background shape exists as a distinct layer on an open canvas. You can select, drag, stack, and align elements with complete creative freedom. Previewed restricts you to preset template structures and coordinate sliders, making custom multi-layered compositions or non-standard device overlaps difficult to achieve.
AppGrowthKit includes helper design tools like the Screenshot Beautifier. In one click, transform raw screenshots into beautifully formatted marketing mockups with soft drop shadows, rounded corners, and customizable gradients - perfect for Twitter, Product Hunt, or blog posts. Previewed is strictly limited to standard app store resolutions and offers no marketing asset tools.

No. AppGrowthKit does not support fully adjustable 3D angles or custom device pitch/yaw/roll. AppGrowthKit focuses on clean 2D and isometric device mockups that keep focus on the app interface. If you require highly customized 3D angles or realistic light reflections on a 3D model, Previewed is the specialized tool for that.
Currently, AppGrowthKit only supports static image exports. We do not support video rendering or animated device mockups. If your marketing strategy relies on showing your app interface inside a moving 3D phone or rendering MP4/WebM previews, Previewed is the right tool for that specific requirement.
Yes! AppGrowthKit's AI generator is built to write high-converting copy in addition to setting up layouts. It analyzes your app description and generates concise, action-oriented headlines that fit perfectly onto your screenshots.
The Screenshot Beautifier is a dedicated companion tool within AppGrowthKit designed for social media and marketing. Instead of full store screenshot sets, it allows you to quickly wrap a single screenshot in an adjustable device frame, add background gradients, adjust padding, and apply drop shadows. It is perfect for sharing progress on Twitter or launching on Product Hunt.
