In-app subscription apps

Question

Does anyone know of an app that implemented an in-app subscription?

EDIT

====

Just to be clear I'm referring to implementing an in-app purchase of type "subscription" as apple defines it and not implementing a consumable and calling it subscription.

=====

I thought about how the subscription model can be implemented and always ends up with more problems to every possible solution I can think of, so I'm wondering if anyone knows of an app that actually does that.

Thanks

FitnessBuilder (http://www.pumpone.com/fitnessbuilder.html) implements In-App Subscriptions. Let me know if you have specific questions about how the subscription system works.

Answer 2

I don't know of a specific app that has implemented in app subscriptions, and that strikes me as being "not a programming question." But Urban Airship offers a hosted in app purchase solution which does have support for subscriptions:

This might be used to buy a new map pack, game item or subscription based content.

I think you will mostly need to implement the exact mechanics of the system yourself. Users will need to "renew" their subscription by making separate in app purchases.

I've seen MotionXGPS Drive do that... They have a rate of $2.99 a month or $24.99 a year. You still do however, have to renew it manually.

Answer 4

One way to detect if the product is of the subscription type is to purchase it twice. The second time you do it, you'll see a message that warns you about the nature of the product (subscription) and the kind of purchasing (renew).
