Totally confused – What's Up? A Mental Health App Review

The concept is great. However. When you first use, no log in is required. Then, after writing something on the Forum, was told I needed to sign in. No link given. Then, once I finally figured that out, I cannot get back INTO the Forum. Can't find it. Totally not instinctive to get around the stupid app. Not easy to use/save/see what you put in Diary section. Frustrated enough I may delete the thing. ?
