Not that good.

Ive had this app for a few months now. They keep releasing the results for polls, and the winners chosen for voting in them. The problem is, they never let me take the quizzes/polls. Missions and surveys seldom come available, and when they do, it can take months for them to credit. There are many other apps on the App Store which are far superior to iPoll. I wouldnt waste time with this particular app.
