Which Windows equivalent should I use since it doesn't support Windows? It will help if it is just as much feature rich as Bookworm and just as much easy to use as Bookworm. Calibre, is therefore ruled out.
You can try BookFusion. A cross platform reader for Desktops(via Web) with native apps for Android and iOS devices. You will be able to read your eBooks on Windows but also on your mobile devices while having your eBook collection, bookmarks, comments and highlights synced. You can learn more at https://www.bookfusion.com/reading/cloud-library
This is great!
Nothing else googling has the required features this one has.
Thank you and Thank HN for superseding Google!
