In the Middle

I like this app quite a bit and it worked really well in the beginning. It started to jam up and ask for payment later, so therefore I stopped. If you want to just check something just this once, I would recommend it. If you want to start using it more often than that, perhaps try another software.

Nothing Special

I used a snippet from a fiction I'm playing with, the spell check was pretty good and easy to use, but I couldn't try out anything past that without upgrading to a paid subscription so I couldn't see how it would truly work. When looking at getting to the whole document to save changes outside the app I could only see what changes it made in a layout and not even trying to email the changed doc. showed it like the layout in app instead of a document. Would recommend having it make changes to the document instead of separately and allowing for first time users to have one full run through to see how it works before directing them to the subscription page.

Cheaper, but cheaper is not always better...

This app makes a lot of promises: to find spelling and grammar errors, to detect plagiarism, and to rephrase or reword sentences. Unfortunately, the app isn't magic and can't fully deliver on all of its promises. Spelling and grammar errors are detected, and for free, I might add. However, many of the spelling and grammar errors detected were not, in fact, errors. Also, for the source highlights parentethical citations as grammatical or spelling snafus. All issues of plagiarism were not detected, especially when I changed just a few words. Regarding the rewording and rephrasing, I'll just stick with my original ideas. While much less expensive than Grammarly or Hemingway, it isn't quite as smart as they are either.
