Although FBReader does not have the popularity of Caliber as an ebook reader for Windows, it is a good option for mobile devices, such as tablets or phablets, since its package is not as heavy or consumes as many resources as other reading apps. It has the option to add plugins and add-ons that make it easier for us to customize the application and it is also a free application. FBReader has a connection to virtual hard drives and online libraries, so we can read ebooks in epub format that we have anywhere, not only on the device and we can also use it anywhere we have an Internet connection.
