[OS X TeX] iPad app for LaTeX

[R Martinez]

All,

Has anyone tried to use the iPad app for LaTeX called TeX Touch? I will appreciate comments about this app.

I ask the list about this because there does not seem to be a way to try the app first without buying it.

Back in July there was a short thread about TeX Touch on OS X TeX.  And the reviews on the Apple app store are very complimentary. What is the recent experience? 

Thanks in advance.
