[ExtensionPay](https://extensionpay.com) has made over $200 to date with $100 of that in the last 30 days! And it's made over $4000 for my users! Woo! This is starting to feel like real money! There's also a new signup every couple days, so it feels like traction is starting to happen.
Well since Apple allows RevenueCat to operate for iOS/Android devices it seems likely that they should have no problem with ExtensionPay but of course I have to test it. At the very least ExtensionPay will provide an easy overlay over Apple's existing payment system if it's not possible.
