Very good app it shows all the fonts, handwritings,colors,page background,even if it is gradient,hatching and bitmap, but there is a low point which is tge reason for me to give 3 star ⭐ for this app because it doesnt show the slideshow,custom animations,sounds,and slide transition. Who wants all the above features they cannot use it.

I use this to read Wordperfect documents on my android phone. It's a fast, accurate viewer and enables me to read Wordperfect documents when I'm in court or away from my computer! Corel should be ashamed for not having a free WordPerfect document editing app!!!

Handy device to keep up with my finances, on screen readout is exactly as the spreadsheet. Works well from a Dropbox saved document. Problem is that dates are still numerical instead of ddmmyy format, and tabs are just additional in the scroll, rather than separate identities.
