I am using Outgrow to segment my visitors and customers so I can deliver RELEVANT content in a dynamic way that works intuitively according to behavior. Calculators or quizzes do just that! it brings information in a FUN interactive way and as a result Customers and Visitors spend more time on my site. For Visitors I can use the quizzes for lead generation, again I am able to deliver relevant content and send hm to a funnel that better suits their needs. For Customers and Students and I find out what they would like to learn next and create new relevant courses, Its pretty simple to create those calculators and quizzes and embed them on your site or you can use a custom domain and have them host them for you. You can also use your own logo which is a nice tough. Last but not least... The support was on point and helped me every step of the way.

I like the UI of the calculator but setting up logic and other things is a bit complex.

I have been looking for quiz software for awhile. I looked at many of the popular and not popular ones. The great thing about this is it has 3 types of quiz styles, and are as robust as anyone. They have a trial period so you can test it. I can add any type of graphic including animated gifs. The support is great, they answer questions right away.
