Confusing Apple In App Purchase products

Question

I am creating an note taking app like Evernote for iPad. I decided to provide some In App Purchase plans for 2 reasons.

1. Unlock more features in app.
2. Should be Auto renewable after specified time period.

Now i have confusion which type of In App Purchase to select for this. I am interested in Auto-Renewable Subscriptions

After visiting the guidlines here, i found

You may sell and unlock additional functionality within your application using In-App Purchase. Adding additional functionality to an app should generally be considered Non-Consumable.

But Non-consumable are not Auto-Renewable.

So which type of product should i choose?

Does Apple approve unlocking app features with Auto-Renewable Subscriptions?

Also, after purchasing a plan, on how many devices user can unlock(restore) features with same Apple ID?

Answer 1

Beware of using Auto-Renewable subscription becuase Auto-Renewable subscription's world is very small. 99% of the apps gets rejected in this case. Basically apple allows Auto-Renewable subscription for apps those follows:

• Newspaper, Magazine
• News Stand
• audio/video streaming feeds
• membership to a dating service
• Business app providing cloud storage services

you can read a well defined document (page 4) by apple here:

https://developer.apple.com/in-app-purchase/In-App-Purchase-Guidelines.pdf

A application of mine got rejected with these comments by apple:

We found that the Purchasability Type for one or more of your In-App Purchase products was inappropriately set, which is not in compliance with the App Store Review Guidelines.

Cloud-books is set to Auto-Renew Subscription.

Based on product functionality, it would be more appropriate to use the non-renewing subscription In-App Purchase type. The Auto-Renewable Subscription product is best suited for apps that require or feature dynamically or frequently changing content, such as digital periodicals or radio subscriptions.

Non-renewing subscriptions can still be offered, but auto-renewable subscriptions are now preferred for the following reasons

I have submitted app today with non-auto subs and see now they approves it or not, otherwise finally I would have to make if consumable with some server mechanism of forcing user to buy it again after a certain time period.

Go through this thread, might me useful for you:

iOS recurring subscription policy for service, not content

UPDATE: My another app on auto-renewable subscription got approved by apple. Before approval it got 2 rejections. First for insufficient content in IAP Product identifiers and second for insufficient application description.
