The app is for people who want to make money and have a lot of time. It works so ,that users of app watch ads , spin wheel and choose daily bonus.You get several coins for each ad and you collect them until you have a certain amount of coins(set to 500,000 but can be changed).If admob disapproves your ads, you can add another ad platform there. Then the user can change coins for real money Basic version not include OneSignal PushNotififacion but if you want it , please contact me. .
I used Applovin ads or AdMob in my app. You must create an account .You’ll get enough money from your ads.When the user of the app achieve a certain coins , he will be able to “send” data(more in documentation) in Firebase Database with his PayPal email and the amount of money he will receive for coins.Then you send him money for paypal.This is very convenient for you and the user, because you will both make money from it(because you as the owner of app can set how much money user gets for a certain amount of coins)
