Premium Subscription
Everything related to the Premium Subscription.
What are the differences between the free and subscription plans?
The only single limitation of the free account is that you are limited to interacting with diagrams on several first pages of every book. This limitation makes it quite easy for you to check all the features the Reader has in each of your books before deciding whether to subscribe.
I am on a monthly subscription, how do I switch to the annual subscription?
The easiest way to do it is to:
- Cancel your monthly subscription - you will retain the access to its billing period end
- After the billing period for your monthly subscription is over, subscribe to the annual plan
