Why We Built AppScreens

The challenge

Why screenshot work gets messy

Building the app is only the beginning. Store screenshots sit directly between traffic and installs, but they also have to satisfy platform requirements for sizes, formats, device types, and creative rules. If teams skip screenshot messaging, localization, ordering, and testing, they leave downloads on the table. Public testing examples range from about +4% to +61%, and localization-led ASO examples can go higher, including +101% global downloads and +128% more iPhone downloads. Results vary, but the pattern is clear: screenshots, localization, ordering, and testing are too important to leave as an afterthought.

We felt this most during ordinary releases: a new feature shipped, the interface changed, and suddenly the raw captures needed to become finished store creative across sizes, device frames, and languages. They needed benefit-led captions, visual hierarchy, localization, and a clear first impression before the update felt ready.

Here’s why this task kept taking longer than we expected:

• Store sizes and rules change. iPhone, iPad, Android phone, tablet, watch, laptop, and other outputs all need the right dimensions, ratios, and formats. A set that worked for the last release can need another pass before the next one.
• Generic tools leave production work behind. Figma, Photoshop, Canva, and mockup tools can create good visuals, but teams still need to manage captions, sizes, exports, filenames, localization, uploads, and QA.
• Design should not block a release. Developers need polished screenshots without becoming visual designers before every update can ship.
• First impressions drive installs. Store visitors make quick decisions. Benefit-led screenshots help users understand the app faster and give teams a stronger starting point for ASO testing.

Use general design tools for general design work. Use AppScreens when the job is App Store or Google Play screenshots and speed matters: AI onboarding, app context, ready-to-go templates, AI captions, store-aware exports, localization, variants, and upload workflows make the path shorter than starting from a blank canvas.

Our solution

A screenshot workflow built for releases

We wanted AppScreens to start where the screenshot job actually starts: with the app. Select the app with AI onboarding, pull in metadata, generate or edit benefit-led captions, choose ready-to-go screenshot templates or start from scratch, upload real app screens, customize the design, preview every output, then export or upload App Store and Google Play screenshots.

We had been there: store requirements in one tab, simulator captures in another, and a release waiting on dozens of correctly sized images.

The principle was simple: one project should hold the screenshot story, the source app screens, the device layouts, the captions, the brand styling, the locales, and the exports. If a developer updates one headline or swaps one screen, the whole screenshot set should be able to move with it.

Fast enough for a first release

AppScreens is not only for large teams or complex localization workflows. It is also built for the developer, founder, indie hacker, or marketer who needs a clean screenshot set today without learning a blank-canvas design tool.

Start with AI onboarding, choose a template or start from scratch, upload your screenshots, edit the captions and design, then export store-ready files. Free users can create one project, use AI mode, export up to 5 screenshots, and manually upload them to App Store Connect or Google Play, which is enough for many first releases.

When the workflow grows, paid plans make the same job faster across more screenshots, projects, direct uploads, localization, variants, team workflows, agencies, studios, and client work.

Responsive design for stores and languages

AppScreens keeps Apple, Google Play, and other store outputs in one project, from phones and tablets to watches, laptops and Vision Pro. It is designed around App Store Connect, Google Play Console, Microsoft Store, and other screenshot requirements, so exports are correctly sized and ready to upload.

Localizing your screenshots? Keep every language in the same project and export the full set at once, instead of duplicating designs for each locale.

For a standard cross-platform app with 10 screenshots, 4 output sizes, and 10 languages, that is 400 assets you would otherwise need to make, name, store, and check manually.

Smart export: resize once, export the set

AppScreens sizes your screens for every target output and language, from App Store screenshot sizes to Google Play screenshot sizes, resizing content and text to fit each export size and aspect ratio. That removes the repeated work of dragging, configuring, and resizing each screenshot for each store target.

You can lock device positions, grow to width, lock text size, or match all titles to the smallest size, keeping everything uniform on export.

This is the kind of release work that eats into coding time. Smart Export keeps the set consistent so you can get back to building the app.

Upload to App Store Connect and Google Play workflows

Exporting screenshots is only half the job. The next time sink is opening store consoles, matching each asset to the right device slot, checking filenames and sizes, and repeating the process for every locale.

AppScreens supports App Store Connect screenshot upload workflows and Google Play screenshot workflows, so teams can move from finished screenshot set to uploaded store assets faster. That matters when the same app needs multiple device classes, localized listings, test variants, and repeatable release updates.

AI captions for different store angles

Screenshot captions are not just labels. They decide whether a visitor understands the benefit, the use case, and the reason to keep swiping. AppScreens can draft caption ideas from your app details, with modes including search intent, outcome-led, emoji, direct, friendly, persuasive, and story-led.

Flexible layouts

AppScreens supports custom layouts instead of locking you into one fixed PSD or mockup. You can show features, highlight updates, or build a consistent screenshot story while keeping the project editable.

We've pulled together an extensive library of thousands of devices, device styles, and ready-made layouts, from the latest smartphones to tablets, wearables, and more.

150+ app screenshot templates

AppScreens includes 500+ editable screenshot layouts for App Store screenshot templates and Google Play screenshots. Start with 150+ template sets and 500+ editable screenshot layouts, then export across App Store and Google Play target sizes without rebuilding each canvas.

Use them as tested starting points, export multiple styles, and run A/B testing in your chosen store to measure what actually performs.

Built for store experiments, CPP and PPO

For teams that actively test store creative, screenshots are never really done. AppScreens makes it easier to duplicate a set, change the hook, reorder the first three screenshots, localize a variant, or prepare assets for an ASO screenshot workflow, PPO and CPP screenshot variants, and Google Play experiments.

A/B testing sounds simple until every new style, caption, order, CPP, PPO variant, or Google Play experiment needs new assets. AppScreens makes those variants easier to create, localize, export, upload, QA, and reuse, so teams can let real store traffic decide which message converts.

Screenshot translation

Localization is growth work, not admin. Teams need translated captions, longer-text checks, RTL support, per-language screenshots, per-market images, layout QA, exports, localized uploads, and store checks. AppScreens keeps that work inside one editable project.

Professional localization is still worth using for important markets. AppScreens also lets you localize App Store and Google Play screenshots into 80+ languages with AI translators, automatic text resizing, RTL support, and per-language screenshot or image overrides.

You can also upload app screenshots from a simulator for each target language, keeping localization work in one place instead of scattering files across folders and tools.

More release tools

AppScreens also supports an AI-assisted setup workflow that can pull your app metadata, suggest captions, and get you to an initial screenshot preview in just a few clicks.

From there, you can refine the details with rich text, emojis, custom fonts, text backgrounds, image elements, multi-layer editing, bulk screenshot imports, panoramic backgrounds, Google Play feature graphics, export history, release previews, and direct store upload.

It also includes advanced device frames and device styles, including dynamic frames, clay mockups, themeable frames, and 3D device styles. These details came from real release work: the brand polish, device choices, layout checks, localization reviews, and file-management tasks that happen after the first design looks good.

A repeatable screenshot system

The real value shows up after the first release. When your app changes, your screenshots should not become a one-off design project again.

AppScreens keeps layouts, devices, captions, translations, variants, export targets, and upload workflows together so each update starts from a working system instead of a blank canvas.

Who AppScreens is built for

AppScreens is built for developers, founders, marketers, product teams, designers, agencies, freelancers, studios, and app teams that need store-ready screenshots across releases, languages, variants, and upload destinations.

Use AppScreens when screenshot work needs to stay editable after launch. Use it to update screenshots after a UI change, localize a store listing, create ASO variants, prepare CPP or PPO assets, export required App Store and Google Play sizes, and keep future releases moving.

Over to you

Build the screenshot set without rebuilding every size

Developers who previously spent hours manually adjusting screenshots can keep one AppScreens project and export the store sizes they need. Designers and marketers can test new caption angles and layouts without rebuilding the whole set from scratch.

More than 150,000 app professionals trust AppScreens, and users have exported more than 11M+ screenshots. AppScreens has saved approximately 72,493 developer days using a 3-minute-per-screenshot production estimate. The broader point is simple: screenshot production scales badly when teams add sizes, languages, variants, exports, uploads, and QA.
