What is the best app to win real money?

Could you possibly elaborate on what criteria should be considered when evaluating an app for winning real money? Is it primarily based on the payout rates, the reputation of the app's operators, or perhaps the variety of games and betting options available? Additionally, are there any specific safety measures or regulatory frameworks that should be taken into account to ensure a secure and fair gaming experience? Could you also provide some examples of popular apps that are known for offering legitimate opportunities to win real money? Finally, how do users typically verify the authenticity and trustworthiness of such apps before investing their money?
