Could be a great app, but disappearing text while writing without the option of getting it back via ctrl + z is just a no go. Seems to be an old issue (found many people talking about this on Reddit about a year ago) related to their way of synchronizing the data. Seems to happen especially when having a spotty internet connection. Lost chunks of text because of that, before I stopped using the app. So, beware of that little circling icon when typing. Or beware of the app altogether.
