How it works: There are two ways to earn cash with Survey Savvy. The first is, as the name suggests, by completing surveys (which typically pay between $1 and $3 each). However, you can also make passive income with Savvy Connect, which is a lightweight and unobtrusive mobile app that runs in the background on your computer and/or mobile devices, collecting anonymous data to send back to the company. Savvy Connect users can earn $5 per month per device, just for keeping the app installed. Inboxdollars Bbb Rating
How it works: With Survey Club, you can take part in some of the highest-paying research, clinical trials and surveys available. There are often location-based opportunities (such as focus groups), and unlike some of the other companies on this list, Survey Club often gives you the chance to test products that researchers will physically mail to you free of charge.
