No you cannot do this. Apple does not allow you to put a higher price on iOS than other places. Also the issue is Apple's inconsistency. Netflix and Spotify do the exact same thing HEY is trying to do but Apple has done nothing for them because of this bullshit distinction between consumer and business apps??? Why do consumers apps not need IAP but business apps do?

What they're doing is exactly what mafias do. Look for the weak, force them to need your help or else, then extract as much money as you can.

I love Apple and all their products but this services growth strategy is putting a bad taste in a bunch of people's mouths.
