Question 

How to change the subscription type in the mobile application? For instance, how to change a monthly subscription to an annual or lifetime subscription?

Answer

There is no mechanism to change the subscription type in BCR or FineReader PDF apps. However, the following steps can be taken to switch to another subscription plan:

1. Cancel the current subscription as follows: How to cancel the subscription to Premium Account in iOS application?
2. Request a refund from Apple as described in the article: How to refund the purchased iOS application?
3. When the refund has been granted, purchase the required subscription plan.

Otherwise, please cancel the subscription in the application and wait until it expires. Then purchase the required subscription plan.

Note: A lifetime subscription is available in the BCR app. To switch to lifetime in the FineReader PDF app, the FineReader PDF Pro version should be purchased.
