How Stora generates App Store and Google Play screenshots using AI-powered capture.

Screenshots#

Stora automates the most tedious part of app store listings: generating screenshots for every required device size, styled and ready to upload.

How It Works#

Stora uses a vision-based AI agent to navigate your app and capture screens. Here is the process:

  1. App Launch — Stora boots your app in a simulator (iOS) or emulator (Android).
  2. AI Navigation — The agent explores your app screen by screen, identifying the most important views to capture.
  3. Capture — Raw screenshots are taken at each screen for every required device size.
  4. Design — Screenshots are styled with device frames, backgrounds, captions, and your brand colors.
  5. Export — Final images are exported at the exact resolutions required by each store.

Supported Platforms and Device Sizes#

iOS (App Store)#

| Display Size | Device | Resolution | |---|---|---| | 6.9" | iPhone 16 Pro Max | 1320 x 2868 | | 6.7" | iPhone 15 Plus / 14 Pro Max | 1290 x 2796 | | 6.5" | iPhone 11 Pro Max | 1242 x 2688 | | 5.5" | iPhone 8 Plus | 1242 x 2208 | | 12.9" | iPad Pro (6th gen) | 2048 x 2732 |

Android (Google Play)#

Google Play requires a minimum of 2 screenshots, with a recommended set covering phone and tablet sizes. Stora generates screenshots at standard densities for common device configurations.

Design Styles#

When creating a screenshot collection, you can choose from several design styles:

  • Clean — Minimal device frame on a solid or gradient background with a caption.
  • Bold — Large text overlays with your app's primary colors.
  • Lifestyle — Contextual backgrounds that match your app's category.
  • Minimal — No frame, just the screenshot with subtle rounded corners and shadow.

You can customize colors, fonts, and caption text after generation using the built-in editor.

Using Screenshots#

Web UI#

Navigate to your project's Screenshots tab, click New Collection, and configure your options. Stora handles the rest.

Tips for Best Results#

Tip: Pre-populate your app with realistic data. The AI agent captures what it sees. If your app shows empty states, the screenshots will too. Use demo accounts or seed data for the best results.

Tip: Keep your app in a logged-in state. If your app requires authentication, make sure the simulator/emulator is already signed in so the agent can access all screens.

  • Choose meaningful screens — If you provide screen hints, focus on features that differentiate your app.
  • Test with one device size first — Generate for a single size to preview results before running the full set.
  • Edit captions after generation — The AI generates default captions, but you know your value props best. Tweak them in the editor.
  • Use locale-specific captures — For different languages, generate separate collections so the app UI matches the caption language.
