I have a desktop application that allows the user to use it fully without limiations for a week. After one week, it will validate their in-app purchase status. I'll make a simple case. Let me suppose that the application allows them to draw a triangle. After the expiration, they can still draw a triangle. But it won't let them save it as an image to disk after expiration. For the past several months, many of my desktop applications have this free-for-1-week-with-IAP business style. And I never had a problem with reviewers in this regard. This time, I've been hit with the following rejection description.
Guideline 4.2 - Design
We found that your app provides a limited set of features and functionality to users and is therefore not appropriate for the App Store. Specifically, the app requires an in-app purchase after 1 week to continue use.
Next Steps
We encourage you to review your app concept and evaluate whether you can incorporate additional features to enhance the user experience.
First, I had no idea what the problem this reviewer is saying. I now suppose that he or she has rejected it because the application would be no use after one week. If I'm right, then so what!? I don't really have a problem if every app is treated in the same way. But if this app is rejected because the user will have no use without a purchase after one week, then many of them, if not all, subscription-based apps also have to go? I have asked the reviewer why I need to enterain the user further after one week of free trial. And he or she has ignored my question so far.
So what do you think? Thanks.
P.S. I see a lot of subscription-based desktop applications at Mac App Store. And I had one desktop application several months ago with a subscription IAP. The reviewer rejected it because it's not a news app and therefore the subscription IAP is not allowed, he or she said.
