Automagical but tends to bug out in long, math-heavy docs
The app is very, very useful overall for researchers of any kinds. I’d say if you can get math-heavy documents displayed correctly even if you sell it for 20 euro I and probably many of my colleagues will still buy it. You’ll get rich only selling the app to scientists and university staff… But in math-heavy documents the app tends to bug out. For examples: if you Google “The Matrix Cookbook”, the first result should be a PDF. In the PDF you’ll find many bugs.
