I have a Surface Pro 4, and I’m looking for a simple PDF viewer that works well in tablet mode. I used to use Edge, but after they switched to chromium it lost a few key features for me (pen input automatically being a pen instead of scroll, pen eraser working, full screen page swipe rather than scroll, etc). Everything else I’ve found is either way overpowered and cluttered, or doesn’t work well with tablet mode and pen input. Any suggestions?
I have personally used DrawboardPDF on Windows tablets because it came with one that I bought, but it costs money and there may be better options out there. Nonetheless, it’s probably worth checking out.
Aside from that, I would probably consider looking at Xournal++. It’s technically a note taking program, so probably not quite what you’re looking for, but it handles PDFs and it seems to work well with a stylus. I’ve never used it to any significant extent, however. It’s also free, open source, and cross platform which are major pluses.
