Hi
I released Days of the Year a couple of days ago on iOS - https://itunes.apple.com/us/app/days-of-the-year/id1448209828?ls=1&mt=8
2018 was a sucky year for me, and I looked back and realized I'd spent more time being angry or stressed than what felt healthy, so I made this tool just for me. However, everyone I showed it to liked it and wanted a copy, so I figured I might as well clean it up and release it. The point is to simply get a good overview of your mood, and being able to track it over a year. I've already found that it helps me, it becomes sort of a self-fulfilling thing, you want each day to be at least normal, so you actively try to feel good. Maybe someone here will find it helpful as well.
