Usertesting pays for website and mobile tests. I made a few thousand bucks from them over the last few months.
Check it out, sign up here. First, you must pass a qualification test to become accepted as a tester. If I recall correctly, the signup process should take around 10-15 minutes. So, they're not just handing you the money - you're going to have to work for it. Once accepted, they'll pass out tests, but once they're quotas fill, you can no longer take it, so act quickly. Website tests pay $10 and mobile tests using a mobile webcam pay $15. Some tests get reviewed and the company will assign you a rating based on the average of your last 12 rated tests. It's important to keep your rating high because Usertesting is looking for quality feedback that they can give to their developers so they can create betters apps and websites for a better user experience for everyone.
