RevenueHunt: Recommender Quiz

I used this app to create a quiz for customers and it was very easy to use and straight to the point. A few features I enjoyed were the ability to add block logic and link products to answer choices. If a certain answer choice is chosen, you can customize their results by linking products to those answer choices to be upvoted or excluded. The block logic can be applied on the results page to do the same, customizing results.
