I really like the fact it's all drag-and-drop. Internally, we have discussions on how to build the best registration form. With Flowmatik we can make changes in seconds.
The best feature is the fact that users can send links to themselves so users can continue on a different device (incl. mobile!). Review collected by and hosted on G2.com.
The builder is all drag-and-drop but could still use a bit of UX work. It's unclear your work has been saved (apparently it's auto save). Also, the analytics overview of the flows could be improved. I can see the live number of users and click conversion but I can not see in which step user drop. Review collected by and hosted on G2.com.
