Ratings and reviews

Generally works well for reading Epub files, except at night. Even in dark mode it turns the brightness all the way up when you open a file. I can't read anything at night because squinting at the ultra bright screen gives me headaches. I can't find any way to turn this setting off. If I thought the paid version would fix it I might be willing to pay for it.

Previously great, but like other folks have reported, as of spring 2024, it won't open books due to permissions problems with accessing files on the phone (nor am I prompted to grant permissions again, as other apps do). I've emailed the dev and gotten no response, which has been true for other issues over the years, too. It's a real bummer because I've loved this reader and have lots of notes and bookmarks in it.

I have tried several apps and most overwrite the formatting put into the ebook by the publisher, along with other problems. This is not perfect, but it does the best job of rendering the formatting in the ebook. I appreciate that. Now if only they'd put descriptions of the books in the list, and tags, and get them from the metadata, and from calibre, it'd be almost perfect.
