I use Survey Junkie. It is the number one best survey app I have come across so far. I have cashed out already twice: the first time, it was for $10 and I made it within hours. Then I made almost $20, so basically $30 so far and I haven’t even had the app downloaded for longer than 2 weeks. It’s super easy to redeem. You can do PayPal, gift cards, or cash deposited into any account as long as you have a routing and account #. So, yes, it’s real cash. It says 5 business days before you receive it, but I received mine within 2 days. So, on your free time, just do surveys. You have to have patience. That’s the key. If you do, then that’s the app or site for you. Good luck.
I belong to almost all of the sites you listed and out of all the surveys I take I don’t qualify for 95% of them. I will spend 15 minutes with generic questions with them collecting information about me then when done they say I’m not eligible for the survey or they have reached the required amount of people for that research. I can understand the reaching the required amount of people but I would think I would qualify for at least 1 or 2. It’s really discouraging when you take all that time to do the survey and not even get any points for doing so!
