Reviews

Classy PDF reader
Praxis15

A very smooth first offering from the developer of the excellent KyBook 2. I read a lot of medical journal articles as PDFs and this app really elevates the experience. Having used this for two days I have already started moving all my PDFs into it (from KyBook 2) - it is just a really streamlined and professional reading environment. Pinch to zoom is smooth and renders crisply. The sepia tinted theme is perfect for getting lots of reading done. The minimalist, discreet toolbar at the top doesn't get in the way visually at all. The pop up editing / marking toolbar can be smoothly dragged around the screen - a nice touch. Suggestions : Please add the 'page curl' sound from KyBook 2 ! Tweaking the pencil setting so it renders smoother would be great - it's looking a tad rough at the moment. Please add KyBook 2's text-to-speech ! A very promising app !

Great free reader I have ever met

In translation, Myanmar language is not available but I hope it will be soon. I really love this app.

A great DJVU reader
Iron Pip

This is one of the only djvu readers that lets you edit the outline. It also has the richest set of annotation tools of any djvu reader. Overall a great reader for technical books and documents.
