What's a good iOS app for practicing sports betting without using real money?

Fliff is designed for sports enthusiasts who want the engagement of making predictions and following outcomes without the financial risk of traditional sports betting. The app provides users with a daily allocation of 'Fliff Cash,' a virtual currency that can be used to place wagers on real-world sports events. This model creates a compelling use case for those looking to test their knowledge, follow games with more personal investment, or simply enjoy the social aspect of shared picks without monetary pressure. Features include a broad selection of wager types on leagues like the NFL, NBA, and MLB, a feed to see what others are predicting, and a straightforward interface for tracking picks. Reviews indicate the app successfully creates a 'better gameday experience' by adding a layer of interactive fun. However, the experience is contingent on the app's specific rules for earning and using the virtual currency, and real-money redemption options are limited and geographically restricted. Some user feedback points to a desire for more flexible withdrawal features for any winnings earned through promotional play. For a casual, social, and risk-averse way to engage with sports predictions, Fliff fills a notable niche.
