Yes, they are both free actually. Moodtracker happens to have an upgrade you can purchase if you would like, but it isn't at all necessary. I don't spend much time at all doing my mood tracking. Just a few minutes and I'm done. Both versions have a place where you can make notes about each day/journal, so you could theoretically spend a lot more time doing it than I do, but I tend to just jot down a sentence or two to spark my memory about the day, make a few clicks to do the tracking, take a look at the charts and graphs that can be generated, and I'm done. Both sites have many more features that I don't really use to their fullest potential though.
