This app does not look and feel anything like a proper Apple application.

It messes up styles when corrections are pasted in Pages, it is difficult to install, it is overly complex to use, and the fact that you have to install Rosetta to uninstall it tells how old and outdated it is.

The grammer quality itself is sort of good; it misses some errors but not more than what I have seen elsewhere. It has no option for learning a custom grammer construction, however, which is annoying. Also, I am now waiting for support to get back to me - the entire app stopped working after a few weeks and after wasting about an hour, I had to give up and write to support.

This app doesn't cost much and doesn't offer much value in return. It does get you irritated, though.
