Amazing app, highly recommended

This is really an amazing app. I really wonder why it is not more popular. As a PhD student, I have been looking for an app that would allow me to read research papers in split view and mobile. As most of the paper I read have lots of math, I was never satisfied with all other readers with reflow ability as they cannot successfully reflow math expressions. This one can! It is the best reflow app I used, not only on mobile but also on my Mac. I highly recommend it!

Only issue I have sometimes is that the AI adds an unnecessary linebreak inside a sentence, thinking that a new paragraph has started (and sometimes does the opposite). It is really a minor issue, but if that could also be fixed the app would become perfect.

Thank you! Version 1.8 should work better with figures, and I'm working on better grouping math formulas too.

Great read for PDFs

Often I need to read PDFs and its format is not adapted to mobile.
This app readjusts the size of the font and its layout so I can read it easily. The app also saves the reformatted PDFs automatically.

Could be really good

The app has no contents or bookmarks option and also does not remember last read page and also cashes a lot. These two features would make it much better other than that it’s ok.
