Browser and Mac App:
Click on your avatar in the upper right corner of the MeisterTask app and select My Account.
In the menu on the left, select Settings. Choose your preferred language from the dropdown menu and press Save.
If you're using MeisterTask on your iPhone or iPad, the app's language will be the same as the device language you've selected. To learn how to change the language on your device, please refer to Apple's support page.
Currently, MeisterTask's Android app is web-based, therefore the app's language will be the same one you've chosen in the web app.
