Ecranify's answer:

Ecranify creates true 3D device mockups for App Store and Google Play screenshots — right in your browser, with no installation.

3D, not flat frames — control camera angle, rotation, lighting and shadows, unlike most template-based generators Runs in the browser — no desktop app to install, works on any OS Free to start, pay per export — build and preview everything for free, only pay when you export finished images Newest devices — latest iPhones, iPads and Android phones/tablets Store-ready output — every required size, plus multi-frame carousel screenshots and a bundled app icon generator

Ecranify's answer:

Because it sits in the gap between the two kinds of tools people usually settle for. Flat generators (like AppMockUp or Previewed) are quick but give you static, non-3D frames. Powerful tools (like Rotato) give you great 3D but are Mac-only, paid up front, and have a real learning curve. Ecranify gives you 3D quality in the browser, with no install and no subscription — you start for free and only pay when you actually export. It's fast enough for indie developers on a deadline, but flexible enough for agencies producing screenshots for multiple apps.

Frontend: React, Three.js (React Three Fiber) for 3D rendering, Redux Toolkit, Vite 3D geometry: CSG computed in Web Workers for smooth device mockups Backend: Node.js, Express, Prisma, PostgreSQL Auth: Firebase Authentication Infrastructure: Docker, object storage for assets and renders

Ecranify's answer:

Indie app developers, small mobile app studios, and ASO/marketing people who need professional App Store and Google Play screenshots but don't have a dedicated designer. Also freelancers and agencies who produce store visuals for multiple client apps and want a fast, repeatable workflow. Broadly: anyone shipping a mobile app who wants store listings that look polished without learning Photoshop.

Ecranify's answer:

Ecranify started from a common frustration: making App Store screenshots is tedious. Existing options were either flat template tools that all looked the same, or powerful 3D apps that were expensive, Mac-only, and slow to learn. We wanted the quality of 3D mockups with the convenience of a browser tool — something you open, use, and get store-ready images from in minutes. So we built it, and made it free to start so anyone shipping an app could try it before paying. Ecranify is built by Small Water s. r. o.
