From a new language to a publishable locale in minutes

1

Add a language

Select any language from the 180+ supported App Store locales and add it to your active app version.

2

Auto-translate runs immediately

Marteso generates a full localized metadata set -- title, subtitle, keyword field, and description -- right away.

3

Review the keyword field

A 10-to-15-minute review against real search data for that market is all you need to confirm the terms are what users actually type.

4

Publish or sync to App Store Connect

Push your finalized metadata directly or export it for submission -- no copy-pasting between tools.

Auto-translate gets you a complete locale skeleton instantly

Adding a new language is the highest-leverage ASO action most indie iOS developers skip. Marteso removes the friction: the moment you add a locale, every metadata field is pre-filled based on real search data for that market. You review and refine -- you do not start from a blank page.

  • Full localized metadata set generated on language add -- title, subtitle, keyword field, description
  • Keyword field pre-filled for a quick review against real search data
  • Add locales directly in Marteso without switching to App Store Connect
  • All your app versions and their locales in one place
