Hueman is an iPhone app some friends and I created that tracks your relative happiness compared to the last time you checked in. Hueman reminds you to log your mood daily, and presents a beautiful graph of your mood over time.
The interface is extremely simple and beautiful, to encourage you check in often. Color is closely linked with mood, so we chose the main logging interface to cover the visible light spectrum (HUEman).
It was available in the App Store and we had big plans to add new features, but life got in the way and we shelved the project. I’m extremely proud of v1 and would love to pick this back up again some day.
