I don’t want to get into a point-by-point debate on the topic; instead, I want to do something that I haven’t seen anyone do: try to understand why Apple don’t want the sort of free trials that are being demanded.
Apple currently allows free trials in two forms: if you sell subscriptions, you can give customers a free month to try the app; and, you can give your app away free, and offer a free In-App Purchase (IAP) to unlock all features for a fixed period of time.
So why does Apple allow these forms, but not offer a more formal version of free trials? Most developers seem to assume they are deliberately ignoring their protests, for no good reason, or that they simply are not willing to dedicate the resources to solve the problem. I doubt both of these assumptions. I think Apple have probably thought long and hard about it, and concluded that the options they have introduced are actually better than the free trials developer’s are requesting.
