Once we release Cloud Sync and Collaboration we are going to revise the pricing model for Zenreader (at least, with regards to the sync functionality which will be offered as a subscription service).
We do intend to continue offering Lifetime licences (no subscription), but these will increase in price to reflect the added service that will be provided alongside Zenreader with cloud sync & collaboration.
We are still offering Zenreader at a huge 75% discounted price of £39.99 and recommend that you grab your Premium licence before the pricing changes. We are happy to make further discounts if you grab more than one licence (as a lab/group), so please contact us if you are interested.
For those who already own Lifetime Premium Licence - you will have access to Cloud Sync & Collaboration without restrictions.
