Apps on smartphones that offer incentives for users to share them on social media are known as refer and earn apps. Some applications have a referral system that gives users incentives to refer friends who download & use the app, like points, mslots games for freeoney, or discounts. The idea is to reward users for promoting the app and give them the chance to earn more as they refer more users. Businesses utilize this marketing tactic to increase their user base and advertise their goods & services. By encouraging users to become brand advocates in their social circles, it capitalizes on the power of word-of-mouth marketing. This strategy not only improves the app's exposure & user base but also pays devoted users for their marketing efforts.
