The developers state that the program allows to “privately track as little or as often as you want (mood-swings? no problem!), whenever you want (at home, on the go, and even without Internet!), and look back to see your moods over weeks, months, and years to learn about yourself and live better!. “ (Accessed Google Play, October 10 2017). We do not further describe the program due to the score it received in our reviewing process.
