I am currently finalizing my first app, which will support in-app purchases. Users will purchase coins, which can then be used to buy everything else in the store. I have finished setting up the store’s backend to work with purchases using coins. Now, I need to add the functionality to purchase those coins.

My question is whether there is still a significant upside to using a service like RevenueCat, or if I should simply integrate react-native-iap.

The products will be static and consist of eight consumables, which are the coins. Everything else is already set up.
