Doesn't work – Texifier : LaTeX editor Review

I just spent the cost of a glass of wine on an app that is not able to typeset a short file. I have been using latex professionally for many years and published many books and technical papers with it. I thought it would be nice to have an iPad version for simple documents. This app simply does not work. I think Apple should force developers to offer a free trial of their apps, say for one day or even five hours, just to be able to screen out the duds. I discarded the app and took note of the developer. Buyers beware.
