Given that its popularity has ascended to the point where it has become practically a generic name for a survey app, I started my reviews with SurveyMonkey as a baseline package. As it turns out, SurveyMonkey has kept up with the competition pretty well over the years, going far beyond the 80/20 rule one might expect for such a broadly used tool. Both SoGoSurvey and particularly SurveyGizmo—a former Editors' Choice—also represent powerful online survey tools that in many ways exceed what SurveyMonkey offers while preserving much of its look and feel. Any of these would be excellent choices for advanced survey designers. I think SurveyGizmo represents the most capable choice, even though SoGoSurvey has made strong recent improvements in its UI.
“I participated in an in-home product trial study. A coffee machine company sent me one of the coffee makers along with about 200 coffee pods. I received $7 for completing 3 short surveys. Plus, after the study, the company said I could keep the coffee maker. So, I got like 4 mos of coffee for everyone in my household, a free coffee maker and $7!” - David W.
