Hey @Filli you don’t need to create a new app. check out Pragmaflows Translate component on YouTube. Works great. They also have a translation helper, where it exports all the words used in your app to CSV. Then use Google Docs Translate…and reupload the CSV.
Check out Pragmaflow YouTube they have a great tutorial on this. I used it a few months back and was great. Only caveat is that it doesn’t work with collection Data. In this case each collection item would also need to have a “key” I.e input for French, German, Italian etc.
