Add a language to a version

Each version in Marteso can carry metadata in multiple languages. The version detail view shows a separate card for each locale — with its own Screenshots section and App Metadata fields (App Name, Subtitle, Keywords, Description).

Opening a version

1. In the left sidebar, click Versions to expand the section.
2. Click the version you want to add a language to. The version detail opens in the main area.

The existing locales appear as cards below the Latest Build section. Each locale card shows:

• The language name and locale code (e.g., American English · en-US)
• Screenshots — pulled from the latest build for that locale
• App Metadata — App Name, Subtitle, Keywords, Description

Adding a new locale

To add a language that isn't already listed, scroll to the bottom of the version detail view and look for an Add Language option, or use the dropdown on the Push Metadata button to access locale management.

For each new locale, fill in:

Field	Limit	Notes
App Name	30 characters	Your localized title — research the primary keyword in the target language
Subtitle	30 characters	Complement the title — don't repeat the same keyword
Keywords	100 characters	Comma-separated, all in the target language
Description	4,000 characters	Lead with strong copy in the first 250 visible characters

Translated text is often longer than English — verify character counts after translation, especially for German and Japanese.

Read-only versions

Versions with a Read-only badge (typically versions that are already Ready for Sale on the App Store) have locked metadata. To update metadata for a live version, create a new version and edit the fields there, then push the updated version.

Pushing localized metadata

After filling in the locale fields, click Push Metadata to send the localized metadata to App Store Connect. Marteso pushes all locales within the version in one operation.

See the Localization guide for a full keyword research and copy review checklist before pushing localized metadata.
