It's called IMoodJournal and is very simple which I need and allows me to make notations on my moods which is helpful. I'm pretty sure it was either free or very low cost. It's been helpful in that my husband promised I'd improve and the app indicates I am in many ways. The trick will be continuing when very depressed or stable but I'm hoping I can keep up with it. It chimes at night to remind me so as long as I'm near my phone I remember. My mood is low and high and the same time so I guess I'm mixed. I just hope I continue to improve cause I've got a long way to go.
