Premium Membership

Everything related to the Premium Member account.

What are the differences between the free and Member accounts?

The only single limitation of the free account is that you are limited to opening around 15 first diagrams in every book. The member account doesn't have that limitation so you can open all the recognized diagrams in your books. This limitation makes it quite easy for you to check all the features the Reader has in each of your books before becoming a member.

I am on a monthly subscription, how do I switch to the annual subscription?

The easiest way to do it is to:

  1. Cancel your monthly subscription - you will retain the access to its billing period end
  2. After the billing period for your monthly subscription is over, subscribe to the annual plan
