KooBits alternatives
A collective shelf for your ebooks – read, organize, and manage all your ebooks in one place. KooBits can open popular ebook formats such as PDF, EPUB, XML, HTML, KBJ, and more. Personalize your ebook with the Highlight and Stamp to mark important sections or use the Extraction tool to copy content and piecing them however you like in the scrapbook. The best KooBits alternatives are: Alfa Ebooks Manager, Calibre, AlfaReader
I was looking for a pure reader to replace Calibre and/or the Firefox epub plugin for reading epub files. Koobits doesn't deliver at all. Back to converting epubs to mobi in Calibre and using Kindle for PC to read them for me.
