Ah, yes, now I have it.
The upgrade option description inside the free Mantano is rather scant, but inside the Play Store, you get to read what you can see below in the screenshot.
Some of the features advertised there sound really appetizing, such as:
- themes customization
- attach freehand notes (!) to a selection or a page (I'd love the option of freehand notes in Marvin!)
- customize predefined gestures and key actions
- download offline dictionaries
- Notes Manager
If all these features work as well in Mantano Premium as they are advertised, they might make Mantano better than Moon+ Reader, and better than the current Marvin in
some respects, too. Mantano also supports reading PDF files (I guess that's where the freehand notes support comes from) and Adobe DRM.
Given all that, the Mantano Premium price of $10 might be justified. There is also an "intermediate" version, called Mantano Reader Essentials, at $4.
