I've seen several posts (mostly from 3+ years ago) asking about implementing a "home-rolled" free trial for subscriptions in iOS. I'm still a bit confused though as there doesn't seem to be a definitive answer.
I'm wanting to try to increase registration -> free trial conversion by offering users a time-based free trial from my backend rather than going through StoreKit. It will be clear up front that it's a subscription service and has a cost, but they won't need to agree to the auto payment after X days.
Is anyone currently doing this without getting rejected or is this still considered a no-no by Apple?
