There should be a possibility to define a language by worker to use the warehousing app. Right now there is a mix of languages when using the app on a "non english device" (and it's not obvious where the settings come from). For example the tabs "Aufgaben", "Details" are in language "de" but  "scan a license plate" is in english. It should be a consistent use of the language.

Ideally there is a setting on the worker (or more detailed on the users) which language to use. Or there even might be a setting on the warehousing app to choose the desired language by the app user.
