We curate our audience by tracking the quality of their feedback across tests - from ratings provided by other companies, payments made, and deadlines met across all of their tests. This helps us invite the best testers to each test.
During the test process, you also have the ability to message testers to provide input on their feedback, rate their feedback, or reject any test submission that is not high quality.
At the end of each test, you also control who gets paid, receives bonuses, and more. You can also ask testers to submit screenshots or login info to your app to verify that they have participated in the test fully.
