Which data will be required here?
Is it like in surveys (opinions, personal preferences) or more private (passport data. location etc.) ?
To add to the great response from Felicisimoiii above 👆
Currently, two types of surveys are supported: mobile surveys and mobile diaries. A mobile survey contains one or several questions and is answered once. A mobile diary can be answered multiple times and tracks consumer experiences with a product or a service for a certain period of time.
