I bought several review programs on AppSumo and I think this is the best.
With ChatSurvey the user experience is much more informal and enjoyable.
Very smooth and well programmed app. Strengths:
-White label (CName)
-Translation in many languages
-All unlimited (users, surveys)
-Reports very well done.
-etc. etc.
"So much stuff" at such an incredibly low price ... don't miss this opportunity
