I like the sync with Google drive. Also the different scrolling options make it easy to read on different devices.

All I want to do is fill in a fillable pdf and the app won’t let me do it. I can’t believe I paid for this trash.

Goodreader is my preferred reader for text files, but it'd be great if it would support 3rd party fonts, like OpenDyslexic, which you can install on iOS, but GoodReader seems to ignore 3rd party fonts.

Best app.
