Cathartic, and helpful. Did not require a log in when I got it. After the update it suddenly wants a log in. Why? This is not helpful. Clicking on app support link, or developer website also takes me to a log in page. I didnt need to do this when I got the app. I dont face book, twitter, or google plus. This is the only available place to write without suddenly having to create an ID. I had really liked the app before, with five stars. Others may be having this log in problem. Thus no reviews. Hoping it is simply a glitch, and will get sorted.
