Sitrus is an app I've built with a small team of friends that is a different take on mood tracking. Instead of asking you to come up with a number on a scale of 1 - 5, Sitrus will just try to understand your actual emotions. Are you happy? Angry? Sad? Sitrus tracks your mood through a fun and easy to use mood quiz and then combines your responses to help you better understand your mood across numerous dimensions.
Sitrus is still under active development and we're looking for people to try it out and let us know what they think. You can download it on either the Google Play Store or the App Store.
