On the one hand Apple payments are really frictionless. There is no way 3rd parties can match it. Plus easy to track/cancel.
On the other hand a lower price is a lower price. But is it low enough to get enough users to enter a credit card?
Combine this with the alternate App Store thing (looks like EU only) and we’re in for some shaking out of what is and is not a good strategy as an app maker with never before seen on iPhone options in the mix.
