Download EPUB Reader for all books on PC

This app works fine on my phone but I'm attempting use use it on my iPad as well so I can read across platforms. The app looks entirely different on the iPad and has almost none of the same features. I'm confused why I'm able to login to Google on the app if that feature is not also available on other devices? I just need something to replace my beloved Overdrive app but it doesn't look like it will be this.

My only, and I mean only complaint is that the contextual menu that pops up with an open book doesn't have a "long press" function that can be edited. I have fat fingers so if I don't move the page quite enough, the ribbons at the top and bottom appear. I'd love to see that as a long press instead of a short press. Or, just increase the action to open it with a longer press than just an instant touch.

Some things EPUB reader NEEDS to fix to get a better score: In text to speech, it needs to recognize contractions instead of saying the "t" separately in words like "can't" or the "s" separately in possessives. The dimming function is terrible. I set it to use my device's dimming, then a few minutes later I touch the screen and it dims so much I can't see screen to fix it. Highlighting just covers text so you can't read it.
