Refer and earn applications function by offering users a special code or link that they can distribute to their acquaintances, family, and friends. Depending on the app's reward system, the referring user receives points, money, dbig boost slots casinoiscounts, or other incentives when someone uses the referral link or code to download the app. By using the referral link or code to sign up, the new user might also get a bonus. After downloading the app through a recommendation, a user can begin recommending it to their own contacts to get rewards for themselves. Because of this, the app's user base grows exponentially as current users are encouraged to refer new users, who in turn refer even more users.
