Far behind other document viewers

I understand that its digital rights protection is excellent, which is why publishers love it, but for us readers, this is a terrible, terrible app. Highlighting capabilities are from the early 2000s (you can’t highlight as if with a highlighting marker, for example), and you cannot even get the thing to zoom in at the page level and stay at that zoom setting. It treats content as one long scroll, basically.

Rubbish app from developers who don’t even respond politely to requests for more contemporary look and feel and capabilities.

As user unfriendly as it gets

Installed this per kids teacher’s request. Impressive hoops to jump before getting it to work. Plus the awful tech support. I’m in tech service business but can’t think of any worse product and user experience that could top this. The existence of this product/service relies heavily on some sort of odd and arranged monopoly. No way it will survive in our contemporary time.

Very difficult to use

This app is very difficult to use. And not at all user friendly...
The zoom in capabilities are not good at all..and takes forever to be able to finish a paragraph, let alone a whole can’t highlight for note take...just overall not user friendly at all...very disappointing when it’s so important to use for school purposes.
