First of all, i am sorry if i am late to this thread. Coudl not help myself when i saw the topic.
I am a math & physics teacher. I got ipad4 so that i cud be off desktop to type all sorts of math question papers with greek symbols. I bought tex writer and i shud say that it it awesome !!! I type all my question papers in tex writer. I can clmpile them offline on ipad itself !! When i am satisfied with the format, i upload the pdf to dropbox. I use my desktop only to print it out as i dont have a wifi printer.
Thanks to tex writer!! I dont need MS OFFICE anymore !!!
Glad you posted your reactions. This is an app that I hope sticks around! Be aware, though, that there are some bogus ripoffs in the app store that look slick but either have functional problems or are ripoffs of others.
The developer of TexWriter seems quite responsive to suggestions. For example, in an update he inadvertently missed including the AMS package, but issued an update with it in when I called it to his attention.
There is another very useful LaTex app called Mathbot. It isn't the complete authoring package like TexWriter, but is very useful for making single equations for transporting to other apps.
