I’m assuming you’re from the UK
The way it is currently:
You use the app for free, and the creator turns on ads to make money from his work. Ads always have trackers, that’s just how they work.
You pay $20 and never see ads again
You pay $15 a month or $100 a year to remove ads and get extra advanced features most users will never need.
What more options do you want to pay someone for a full time app development job?
Nope, UK. I know what the majority of us are like.
