What I like about this KDAN PDF Reader is that it can be used at work, at home, pretty much on any device and for any purpose. Work-related tasks are now much easier for me because contracts and documents can be signed with a digital signature right in the app, reading is more comfortable since I can change the brightness and background in the reading mode. Apart from that, this reader is fairly easy to use, which is what I'm looking for in any application.
