I have looked at other apps - meditation, eft etc. Some have a rating system - how they user feels before they do the practice - how they feel after the practice.
Does anyone have any idea on how I can implement this into my app?
You would need two number properties for before rating and after rating! Then I guess user has to click on a practice in a list to go inside and then you can add two screens for before and after ratings and add star rating component or a slider component on that two screens like @Rozza mentioned and then you can connect the created properties for them and test!
