Previewed Alternative: Boom Screens vs Previewed

Boom Screens is the best Previewed alternative for App Store screenshot creation: where Previewed focuses on 3D mockup animations and video exports, Boom Screens is purpose-built for ASO — with AI localization into 80+ languages, correct pixel dimensions for every App Store device size, and a per-language ZIP export ready for App Store Connect.

Previewed is well-liked for what it does — animated mockups and browser-based video previews are genuinely useful for product marketing and landing pages. But App Store screenshot workflows are a different job, and the tools optimized for animation are not the same ones optimized for App Store conversion. Here is where each tool fits.

What Previewed does well

• 3D animations and video — Previewed's defining feature. You can animate a device rotating, exploding, or floating, and export the result as a video or GIF for landing pages and ad creative.
• No account required — like AppMockUp, Previewed lets you start immediately without creating an account, which reduces friction for quick mockup jobs.
• Browser-based — no download or install required. Works on any device with a modern browser.
• Wide device library — a large selection of iPhone, Android, tablet, and desktop device frames with clean renders.
• One-time pricing option — the Plus plan at $9.99 one-time is appealing for developers who want to pay once and own it.

Where Previewed falls short for App Store screenshots

Previewed is designed for marketing mockups, not for the App Store screenshot submission workflow. The two use cases look similar — a phone with a screenshot inside — but require very different outputs:

• No localization — Previewed has no translation feature. Every language requires a fully manual redesign.
• No AI — there is no AI assistance for translation, copy, or layout adaptation.
• Not sized for App Store Connect — Previewed outputs are designed for visual impact, not for the exact pixel dimensions (1320×2868px, 1242×2688px, 1242×2208px) that App Store Connect requires for submission. You may need to resize or crop before uploading.
• No multi-language ZIP — Previewed does not produce the folder-per-language ZIP structure that App Store Connect expects.
• No RTL or CJK handling — no support for Arabic right-to-left layouts or Japanese/Korean/Chinese font rendering.
• Positioned as mockups, not ASO — the product is built around visual wow rather than the practical workflow of pushing screenshots to the App Store across multiple languages.

Which tool to choose

Choose Previewed if: you need animated device mockups, video exports, or GIFs for a landing page, an ad campaign, or a press kit. Previewed is excellent at that specific job and its one-time pricing makes it a good value for occasional use.

Choose Boom Screens if: your goal is publishing screenshots to the App Store — especially if you target any non-English market. Boom Screens is purpose-built for the ASO workflow: it exports at the exact pixel dimensions App Store Connect requires, AI-localizes all text into 80+ languages in one click, and packages everything into a per-language ZIP. Previewed is the right tool for a product video; Boom Screens is the right tool for an international App Store launch.
