Can I populate quizzes with values from my database?

Yes. You can use the “identifier” property on any given field, including the different fields that need the same value located on separate section on the form. Furthermore, the identifier is used to specify what data should be assigned to each field.

Can this be embedded into my mobile app?

es. Joyfill's mobile native SDK supports raw react native, expo, Swift, and Kotlin. The SDK is NOT a wrapped web-view. The SDK uses all pure native components in order to provide the best possible performance and support for quizzes across apps.

How to control the quiz data input and output?

In Joyfill you can populate the Joyfill quiz or Template field values, selectable options, table rows and more by simply updating the JSON object and following the JoyDoc format. Utilizing identifiers is recommended because it gives you an easy way to identify what data should be pre-populated in each field.

Can I customize the theme of the UI to match my brand?

Yes. You can customize the SDK UI (and the quizzes) to fit your brand and product theme with a simple JSON edit.

Can Joyfill’s quizzes support thousands of fields?

Yes. We handle performance by using a recycler view (and other best practices) to lazy load and render fields in the viewport of the device screen.
