I downloaded blooms td6 on my old android on the google play store but on the iPhone it wants me to pay again on the app store

You are not going to be able to restore purchases made from the Google Play store from the Apple App Store. The only way that can work is that the App developer allows that within the app itself. In other words, you can download the app and then look into settings for options to log in or restore your purchase. It has to be from within the app and the app must allow it.

You don't.

You can't transfer purchases from android to IOS.
