App Store and Google Play screenshots from one editable project

AppScreens is a screenshot production workflow for app teams that need polished, localized, store-ready screenshots without losing hours to manual design, resizing, translation, exports, and uploads.

Developers, founders, marketers, ASO teams, agencies, and product teams use AppScreens to turn real app screens into professional App Store and Google Play screenshots from one editable project. Start with a template, add AI captions, apply device frames and brand styling, localize across 80+ localizations, create ASO variants, then export or upload the correct store-ready assets.

Questions & Answers

As answered by people managing Diff Checker and AppScreens.

Why should a person choose your product over its competitors?

AppScreens's answer:

AppScreens is built for repeatable screenshot production, not just one-off mockups.

Teams should choose AppScreens when they need to create polished App Store and Google Play screenshots across sizes, languages, variants, releases, and upload workflows from one editable project.

Unlike generic design tools or simple screenshot makers, AppScreens combines:

  • Responsive screenshot projects
  • Professional templates
  • AI captions
  • AI translation across 80+ localizations
  • RTL support and automatic text resizing
  • Per-language screenshot and image changes
  • ASO variants for PPO, Custom Product Pages, and Google Play experiments
  • High-resolution PNG exports
  • App Store Connect upload and Google Play workflow support

It is built for developers, founders, marketers, agencies, and product teams that want store-ready screenshots without rebuilding every file by hand.

How would you describe the primary audience of your product?

AppScreens's answer:

The primary audience for AppScreens is app teams that need professional, store-ready screenshots without losing hours or days to manual screenshot production.

AppScreens is especially useful for:

  • Mobile app developers
  • Indie founders
  • ASO marketers
  • Product teams
  • Designers
  • Agencies and freelancers
  • App studios
  • Mobile marketing teams

These teams use AppScreens to turn real app screens into polished App Store and Google Play screenshots, localize them across 80+ localizations, create ASO variants, and export or upload store-ready assets from one editable project.

Which are the primary technologies used for building your product?

AppScreens's answer:

AppScreens uses a combination of responsive design technology, AI-assisted content workflows, localization tooling, and app store upload integrations to help teams create store-ready screenshot assets.

Key technology areas include:

  • Responsive screenshot generation
  • AI captions
  • AI translation
  • Automatic text resizing
  • RTL localization support
  • High-resolution PNG export
  • App Store Connect workflows
  • Google Play workflows
  • Device frame and mockup rendering
  • Template-based screenshot design

What makes your product unique?

AppScreens's answer:

AppScreens is unique because it combines screenshot design, localization, ASO variant creation, export, and upload workflows in one repeatable project.

Instead of creating separate screenshot files for every device size, language, store, and experiment, teams can create one editable project and generate store-ready assets for App Store and Google Play.

AppScreens supports responsive resizing, AI captions, AI translation across 80+ localizations, RTL support, automatic text resizing, per-language screenshot changes, professional templates, device frames, high-resolution PNG exports, App Store Connect upload, Google Play workflows, and ASO variants for PPO, Custom Product Pages, and Google Play experiments.

That makes AppScreens stronger than generic design tools or one-off screenshot generators when teams need screenshots that stay reusable across launches, app updates, localization, and testing.

What's the story behind your product?

AppScreens's answer:

AppScreens was built by app developers who were tired of losing release time to screenshots.

Every app launch, product update, localization push, device change, ASO test, and store upload created more manual work: new sizes, new captions, new exports, new languages, and new chances to make mistakes.

AppScreens was created to turn that work into one repeatable workflow. Teams can start with real app screens, add templates, AI captions, device frames, brand styling, localization, and ASO variants, then export or upload store-ready assets for App Store Connect and Google Play.

The goal is simple: screenshot production should feel like a build artifact. Update once, generate every size and language, then publish with confidence.

  • How to convince someone lossless compression is possible?
    In what way did you show the file comparison? Did you use a diff like diffchecker.com ? If someone can see for themselves that every bit of data between two files is exactly the same, and still thinks they are different, IDK how you could get past that. x == x is pretty fundamental.

  • Advanced Diff Checker?
    How do I find the actual difference between two strings that appear equal to the naked eye? I used multiple tools and some show no differences, but some show differences. I got diffs on diffchecker.com, but it just shows me that they are different, but not how they differ. Is there a better tool for this? Source: over 3 years ago
  • Is there a library that allows to easily do diffchecks between two json?

    After the app ideation, the code, and a bit of testing here and there, it was finally time to get it out there, on the Google Play Store to be more specific, though the App Store version will be coming out soon enough. Doing that involved generating an app icon, app screenshots, a feature graphic, and some catchy text of course.
