To satisfy 21 particular pricing needs, developers can also adjust these prices manually. 22 </li> 23 <li><strong>Pricing Templates</strong>—Developers can add pricing 24 templates and link these templates to app prices or in-app product prices. 25 These templates include local prices across all markets.

For example, a sports-related service might lower the subscription 33 price halfway through the sport's season.</li> 34 <li><strong>Free Trials</strong>—Content providers can 35 offer free trial periods for all kinds of subscriptions, including 36 seasonal subscriptions. If a user cancels the subscription in the trial 37 period, they pay nothing. If they do not cancel by the end of the 38 trial period, the subscription automatically converts to a paid 39 subscription.</li> 40 <li><strong>Subscription Upgrade/Downgrade</strong>—A user can 41 subscribe to a higher or lower tier of subscription while their current 42 subscription is active. The old subscription is canceled, and the unused 43 portion is applied on a prorated basis to the new subscription.</li> 44 <li><strong>Manual Subscription Renewal</strong>—A user can purchase 45 a subscription at the current rate while their existing subscription is 46 still active.
