Blocs is localised into English 🇬🇧, Dutch 🇳🇱, French 🇫🇷, German 🇩🇪, Italian 🇮🇹, Japanese 🇯🇵, Portuguese 🇵🇹 and Spanish 🇪🇸. The default language that Blocs will use for the user interface will automatically match the selected language for MacOS.
Customize Language
If you would like to use Blocs in an alternative language to the one you have MacOS set to, you can customize the language via the main application preferences.
