That’s true, but it’s also possible to release apps individually on mobile similar to PC releases.
We also currently get the worst of both worlds with stuff like Goodnotes. They had a one-time buy, but currently they’ve injected AI-related nonsense into v6. They allow owners of the previous version to still use v6, but it’s extremely crippled and functionally worse than 4 or 5. Constant nagging about the new version and features. V6 fully replaced v5 on the App Store, so we can’t do anything about it now. Even in my purchase history, my purchase was forcibly “upgraded.”
What I paid for was a digital notebook app that I could write down notes on with my Apple Pencil and iPad. It had a few nice features I didn’t really need, but were nice to have like writing-to-text replacement. It had cloud backups, but they were through iCloud or OneDrive on the user’s individual storage so I’m assuming it didn’t add a monthly cost overhead to the developer.
Now it’s a subscription model app with features I don’t want nor need that completely replaced the app I paid for.
Don’t screw over small indie devs.
