I have seen apps that read CHM or PDF but not both. I need an app that reads PDF as well as CHM quickly and smoothly. I tried OliveOffice but there are issues with landscape mode. Is there any other ?

  • EzPDF is a realy nice PDF Reeder.

  • For PDFs I recommend Mantano Reader.

Moon+ Reader reads chm's and almost anything

  • I confirm that Moon Reader can open both PDF and CHM. It can also open epub and other formats.

  • Meanwhile even Mobi. Almost nothing left except for DRM -- which is not the author's fault (trouble with Adobe not reacting on his queries). I use that app almost for 2 years now, amazing development for a one-man-show!

As you said OliveOffice

or have you tried: iReader

Here is an e-book reader list if you want a 4th option:
