fast and light It's the already open and poured 2% milk to their buttermilk. It isn't as feature rich, (or tangy?) but is such a relief to use for quick references. It loads so quickly, I sometimes forget it isn't already running. It does have TOC, reflow, and a few other simpler capabilities. It's lean first and foremost. It's no full fledged epub reader, and even failed to load one for me. I wouldn't go without it, though, and it is my go-to viewer for PDFs, for its awesome responsiveness.
The fastest and lightest ever made Simply the best lightweight PDF reader for Linux, Windows and Android. A pity that there is no annotation/highlighting feature, even a minimal one would be very useful. Moreover, screen always on should be added. With these features it would be possible to fully replace other much heavier and more complex readers
Fast? Really? Limited functionality Screen space not used efficiently, letting unused space on top and bottom. Very limited menu with few possibility
It lacks important features While it is very fast, it does lack lots of vital features. Vertical scrolling, jumping to pages, remembering the page it was on and keeping the screen on are ALL missing!
Fastest PDF reader I've seen for Android up till now. Great performance even on low-end tablets. Simple but effective flow for reading: Tapping on the right side of the document either advances to the next page or, if you are zoomed in, moves to the next unread part of the page. Perfect for Calibre Companion users bzw. Also: No Ads, no in-app purchases. Software is open source, code is available from Artifex (makers of Ghostscript).
Screen turns off Useless if there is no control to keep the screen lit
