Chat-built App Store sets with auto-written headlines vs a drag-and-drop editor with 3D rotations and MP4 promo videos. Both do panoramic; the difference is how you build them.

Quick verdict: Both tools ship panoramic App Store sets, so panoramic is not the deciding factor. Pick Previewed if the deliverable is a 3D device rotation, an MP4 promo video, or desktop and social mockups, or if a free 720p tier with attribution is enough. Pick AppScreenshotStudio if you want the whole set written and generated from one chat prompt, want REST or MCP access from $7.99/mo, or ship Apple Watch Ultra screenshots. Previewed is the manual designer's tool; AppScreenshotStudio is the solo dev's "get me to a finished set" tool.

App Store screenshot tools generate the marketing screenshots iOS and Google Play listings require. They range from template-based design editors (Placeit, AppLaunchpad, Screenshots Pro) to AI-driven zero-decision generators (AppScreenshotStudio). The best tools handle device framing, exact dimensions (1260×2736 for iPhone 16 Pro Max, 2064×2752 for the 13-inch iPad Pro), and Apple's 60/40 UI-to-marketing ratio automatically. The wrong choice costs hours per app or, worse, triggers App Store rejections.
Original observation
Previewed Lite is free with unlimited 2D exports at 720p but requires Creative Commons attribution; AppScreenshotStudio is free with 10 credits, no attribution, and full export rights on paid plans from $7.99/mo.
AppScreenshotStudio
Purpose-built screenshot generator. Describe your app, see a first draft with auto-generated headlines and layouts, refine via chat until it clicks.
Best for: Developers who want to iterate to the right design, not start from a blank canvas
Previewed
Template-based mockup generator with 3D device rotations, MP4 promo videos, and a free 720p tier. Covers App Store screenshots, social media mockups, and desktop/web frames. You pick a template, arrange elements, and type your own headlines.
Best for: Creators who need 3D mockups or MP4 promo videos

AppScreenshotStudio
Describe your app in a sentence. Headlines, layouts, brand colors, and panoramic backgrounds generate together. Previewed gives you a blank template to fill in yourself.
One wide cinematic image sliced across the whole set, generated in a single pass. Previewed supports panoramic through Partitions, but you assemble it manually in the editor.
Ship screenshots from CI/CD, a terminal, or a Claude/Cursor agent on the Growth plan ($14.99/mo annual). The MCP server is a published npm package. Previewed does not publicly advertise API access.
Render Apple Watch Ultra 2 screenshots with a dedicated 410x502 frame and device specs. Previewed does not list Apple Watch in its device library.
Previewed
Rotate devices in free 3D space and render from any angle. Previewed pitches "studio-grade 3D rendering" and animated angles. AppScreenshotStudio offers 9 preset perspectives but not free-angle 3D.
Export mockups as promotional videos at 60fps on the Pro plan. Useful if you need animated content for social ads, not just static App Store screenshots.
Lite plan exports unlimited 720p mockups with a Creative Commons attribution requirement. Good for side projects where attribution is acceptable and 720p is enough.
Supports MacBook, iMac, generic web browser frames, and social media mockup formats (Instagram, Facebook, X, LinkedIn). AppScreenshotStudio only targets App Store and Play Store.

AppScreenshotStudio
Chat generates the whole set: headlines, layouts, panoramic, brand colors. Free to try, from $7.99/mo.
Previewed
3D rotations, MP4 promo videos, desktop/web/social mockups. Free 720p with attribution, $9.99 one-time, or $19/mo.
Previewed is a drag-and-drop editor: pick a template, arrange the device and text yourself, type your own headlines, export. AppScreenshotStudio is chat-first: describe your app, the full set generates with headlines written and brand colors extracted, and a Konva canvas sits alongside the chat for manual tweaks. Both tools produce panoramic App Store sets; the difference is how you build them.
Yes. Previewed offers panoramic mockup sets through a feature called Partitions, where you set how many images the panorama spans and assemble the layout in the editor. AppScreenshotStudio generates panoramic sets directly from a chat prompt, so you do not arrange the partitions yourself.
No. Previewed has 3D snapshots that render your device from any angle and an MP4 app promo video maker. AppScreenshotStudio focuses on static App Store and Play Store screenshots with 9 device mockup perspective variants (flat, isometric, landscape, side-profile, etc.) but no free-angle 3D or video export. If 3D rotations or promo videos are the deliverable, Previewed is the better fit.
Previewed Lite is free with unlimited 2D exports at 720p (Creative Commons attribution required). Plus is a one-time $9.99 fee for 10 high-res exports. Pro is $19/month. AppScreenshotStudio is free to start with 10 credits, then from $7.99/mo (annual) for 75 credits with full export rights and no attribution. For a one-shot project, Previewed Plus at $9.99 one-time is cheaper. For ongoing work, AppScreenshotStudio starts lower.
No. Previewed is a drag-and-drop canvas editor with a template library. You pick a starting template and customize every element manually. AppScreenshotStudio generates the full set from a chat prompt and writes headlines, picks layouts, and extracts brand colors for you. The visual canvas editor is still available when you want manual control.
AppScreenshotStudio was built for solo indie developers who want finished screenshots, not a design project. Chat handles the full set; App Store and Play Store compliance is enforced automatically; REST API and MCP server access ship from the terminal or CI. Previewed is better when the deliverable is a 3D rotation or an MP4 promo video, or when a free watermark-attribution tier is enough.
