Hi guys,
I have just released a new slim pdf annotation app that targets those of us who want to annotate while we are reading documents. This app is not for note taking (for those who need that I recommend Papyrus).
My app is the slimmest PDF reader, with pen and marker annotation, I have seen. It is easy to use, and it allows you to annotate and highlight as you read. Exactly as you do on paper. It is extremely easy to switch between the pen and the marker; and to toggle colours.
Also – the app recognizes the difference between your finger and the stylus. Fingers are used to move, zoom and erase. The stylus is used to annotate.
A free version of Stylus Annotator is available on Play. Please try it and rate it.
