Cashback apps are mobile applications that allow users to earn money back on their purchases. When you shop at participating retailers, these apps provide a percentage of your spending as cashback, which can be redeemed later. Users typically need to link their credit or debit cards, or upload receipts to track their purchases. Many cashback apps also offer special promotions and bonuses for specific products or stores, making it easier to save money. Popular examples of cashback apps include Rakuten, Ibotta, and Fetch Rewards. These apps are designed to help consumers maximize their savings while shopping both online and in-store.
