i just learned of this one last week and thought i would give it a shot. citizenme is based out of london but is available globally. they ask questions to develop 'your profile' and say the more of these 'insight' questions you complete the more paying surveys you will receive. i only filled out 2 insight activities and already received my first paying question! took under a minute to complete and they paid me within minutes to my paypal. they actually pay in british pounds so the 10 cents actually converted to 12 cents US dollars-score! i actually allowed notifications so that i am alerted to any paying activities and therefore not wasting a bunch of time checking the app all the time.
you can check them out on fb page too. so far i am liking this app. i even went back and connected my twitter account and completed all my pending insights to see if i start getting even more paying surveys. they do not seem to have any referral program that i see. but even if it's a bit of change each month you can't beat instant deposit to your paypal account!
