Difference Between Leben in Deutschland and the Einbürgerungstest

I am applying for a permanent residence permit and the application page mentions the following:

• Certificate of successful completion of the “Test Leben in Deutschland” (Living in Germany test),
• Certificate of successful completion of the Einbürgerungstest.

These two tests are obviously different from each other. I have also installed two apps:

• Leben in Deutschland
• Einbürgerungstest

Do the questionnaires overlap? There is only one download link on BAMF, so I assume that it is the same set of questions?
