Subscriptions

Subscriptions and subscription renewals to content or services can be offered to customers for purchase. You can offer customers the opportunity to renew their content or service subscriptions using In App Purchase, but be sure to define a reasonable renewal frequency to avoid bothering users with unwelcome reminders. Be aware that you are responsible for both tracking subscription expirations and for renewal billing; the App Store does not monitor subscription duration and does not offer an automatic billing mechanism. Be sure to indicate when an item is a subscription when entering its product information into iTunes Connect.
