The app crashes on a daily basis
One of the worst apps I have ever downloaded to my iPhone, and I have had an iPhone since its invention. If the book you purchased is accessible to you only in this app - you are in trouble. Regularly the book refuses to go up and gets stuck. Even removing the app and reinstalling it again does not solve the problem. Unfortunately, two of the books I purchased can only be read here. Which means I'm not comfortable reading it. It is not clear to me why after so many years of operation of HBreader the company is not willing to devote the attention and resources necessary to upgrade it.
