Lie. Not free.
Do you understand what “free with an app purchases” means? If I have to pay to use the function that is advertised, that means it’s paid not free. Why did you greedy people decide to make it cost money on iOS when it is 100% free on Linux, Windows, and macOS? It’s like iOS is a breeding ground for monetization. I hate Apple. There is not a single thing on the App Store that doesn’t cost money. Again if it is paid, why did you lie that it was free?
