UserTesting is a free mobile and desktop application that allows you to make money online in your free time by sharing your perspective with companies around the world. The app offers you the opportunity to earn money by testing new products, websites, apps, and in-person experiences.

To get started, you only need to submit your email and take a quick practice test to join their global network of trusted contributors. As long as you're at least 18 years old, you don't need any special experience to get paid to test. UserTesting customers want to gather your unique perspective, so all you need to do is share your thoughts out loud using your mobile or desktop device.

Once you've joined, you can browse through the screening questions to match with test opportunities. New tests are released all the time, and you can earn money online by completing one or two tests per week. The amount you'll get paid for each test is shown in your test feed, and all contributors receive payments in USD through PayPal.
