The rewards that participants can earn in the app are made possible by our research partners and customers, who are developing artificial intelligence related to image analysis. These research partners and customers subsidize our prizes because our app participants help analyze images from large datasets of our research partners and customers. After participants win rewards, they can tap on the Profile tab and tap on the icon in the top-left corner of the Profile screen. This screen then shows a log of all the participant's rewards, and they can withdraw their rewards to a payment account.
