Manage your store listings in one workspace
Bring the app’s existing store copy into AppScreens. Prepare the fields and languages together, then review one clear set of changes before saving.
Store metadata, CookBook. App Store Connect (API key · CookBook): Connected; Google Play Console (Service account · CookBook): Connected; Download JSON (Version metadata · 2 languages): Ready; Upload JSON (3 field changes within the limits): Valid; Save to store (App Store Connect · en-GB, de-DE): Saved.
Connect your apps once
Bring your Apple and Google listings into the same workspace using store credentials you control. Return to the connected app whenever it needs an update.
Prepare the update across languages
Start with the current store copy. Export the fields and languages you want to change, then use your preferred AI tool with AppScreens’ instructions to prepare the revised file.
Review every field before saving
Import the update to see the current and proposed values together. AppScreens checks the field limits and keeps each change tied to its app, language and store destination.
Save the approved copy to the store
Apply the reviewed update directly to App Store Connect or Google Play. Complete the store’s review and publishing steps in its console, with your screenshot project ready alongside the copy.

One release, every language
Over 600 fields. No copy and paste.
Localize one release into every language both stores support and the listing copy adds up fast. Instead of editing each field in each store console, download one file per store section, let your AI tool update every language, then review and save the changes with your own API access.
- App Store fields

300 - App Name, Subtitle, Keywords, Promotional Text, Description and What’s New in 50 languages
- Google Play fields

320 +- Title, short description, full description and release notes in 80+ languages

Your AI tool writes. You approve.
Use your preferred AI tool to refresh a description, adapt a subtitle or prepare several languages. AppScreens gives it your current copy and store field limits, then brings the result back for your approval.
Keep your existing copy as the starting point
Export the selected fields and languages as JSON with AppScreens’ AI instructions. Your writing tool gets the structure it needs, so you can prepare the update together instead of copying each field into each store.
See every change before it reaches the store
Import the revised file to compare the current and proposed text side by side. AppScreens checks the field limits and shows the app, language and destination. Save the update when you’re happy with it; unselected fields stay as they are.

App Store and Google Play copy, in the right fields
Manage app names, subtitles, descriptions, keywords and release notes without losing track of where they belong. Each update stays tied to the selected app, store and content destination.
| Store | Content destination | Supported fields | Update context |
|---|---|---|---|
| App information | App Name, Subtitle, Privacy Policy URL, Privacy Choices URL and Privacy Policy Text | App identity and localized value proposition, on the selected app record. | |
| Version metadata | Description, Keywords, Promotional Text, Marketing URL, Support URL and What’s New in This Version | Copy for the selected platform and version, using its available editable fields. | |
| Store listing (app-wide) | App Name/title, Short Description and Full Description | The listing for the connected app and chosen store languages. | |
| Release notes | What’s New/releaseNotes | The exact selected release in its track, with the existing artifact version codes. |

Field limits
App Store and Google Play character limits
Catch text that is too long before saving it to the store. AppScreens checks imported copy against each field’s limit, including Apple’s byte limit for keywords.
Scroll across to see both stores.
| Listing field | App Store | Google Play |
|---|---|---|
| App name / title | 30 characters (minimum 2) | 30 characters |
| Subtitle / short description | Subtitle: 30 characters | Short description: 80 characters |
| Keywords | 100 bytes, separated by commas | No keywords field |
| Promotional text | 170 characters, editable without a new version | Not available |
| Full description | 4,000 characters | 4,000 characters |
| What’s New / release notes | 4,000 characters | 500 characters per language |
Apple keywords count bytes, not characters
The Keywords field holds 100 bytes. Some characters use more than one byte, so AppScreens checks the byte total when you import the copy.
Checked before anything reaches the store
AppScreens validates every imported value against its field limit, then shows a before-and-after review. An overlong subtitle or short description is caught while the change is still a proposal.
See Apple’s version field reference and Google’s store-listing guidance for the content you are preparing.
Keep your apps ready for the next update
Return to each connected app with its store copy and saved screenshot projects in one workspace. Finish one app’s update, then move to the next.
