Twitch charges $5.99 for a subscription to a streamer in their app but $5 on their website. Are they breaking this rule too? How are they getting away with it?
Just add a transparent reporting about how your prices came to be and they will not let you do so.
Pricing $5.99 in-app and $5 outside is a good strategy. It’s a nudge to get users to buy outside the app and save 15%, but if not they’re effectively splitting the Apple tax.
