There are several apps for reading ePub files on Windows. Here is my recommendation for which one you should use:
Aquile Reader
Aquile Reader is Windows 10 style, but does the best job of being overall a good reading app. I recommend the app for anyone looking to read ePubs on Windows. Hopefully the app gets some improvements and WinUI3 love, but for now that is the only thing missing.
- ePub+, Good UI but basic themes and functions of reading missing
- freda, clunky, harsh overbearing UI
