Currently in beta, Pinnion is a survey website that allows users to have access to the free basic version, or while in beta testing get access to the premium account for free. The premium access does mean that they will want your feedback on the service. What makes Pinnion different from the others is that it is compatible with phones and tablets.
Pinnion allows unlimited questions and responses. You also get custom branding and graphics as well as a custom closing message. There is a free WordPress plug-in as well. You can also embed the surveys onto a website as well. There is a quick sharing feature through email and other social media sites. Results for your surveys are available in real time with the ability to filter and report on results. You can also export to Excel/CSV.
You can find the apps for both iPhone/iPad and Android phones as well. So if you are in the market for creating surveys, you might want to give Pinnion a try.
