Routiq.com offers a Premium subscription. You can use a 7-day free trial period prior to the subscription.
The purchase will be charged to your iTunes account. You can change or cancel your subscription at any time via your Apple ID in iTunes ( https://support.apple.com/en-us/HT202039 ). The subscription automatically renews 24 hours before the end of the subscription, with the same subscription for the same price. It is not possible to cancel the subscription while it is in progress. When you cancel it, you keep the premium features for the remaining time, but it will no longer automatically renew.
