What Are Cashback Apps and How Do They Work?

Cashback apps are mobile platforms that reward users with a percentage of their purchase price when they shop through the app's links or partner merchants. Users link their credit or debit cards, make purchases at integrated retailers, and receive cash or digital rewards within days or weeks.

How the monetization chain works for publishers and brands:

• Consumer downloads app (via app store or offerwall).
• App publisher earns install fee (CPI) or cost-per-action (CPA) from brand or performance network.
• Consumer makes purchase through cashback app's affiliate link.
• Cashback app earns affiliate commission from retailer (typically 2–8% of order value).
• Consumer receives cashback (1–5% of purchase); remainder funds app operations and publisher payouts.

NerdWallet identifies Fetch, RetailMeNot, and Coupert as leading US cashback apps, each with 50M+ downloads and strong merchant partnerships.
