One of our readers forwarded to us a story about a new application called MoodRhythm that was developed at Cornell University and won the prestigious $100,000 Heritage Open mHealth Challenge.
The full story is available here.
The application, which is available as a beta, is available for both iPhones and Android smartphones (although how to download it may be a bit tricky because it isn’t yet in the Play store for Android phones and may not yet be on iTunes).
What is most interesting about it is that it seeks to keep track of several important things for you (automatically) – for example it tracks your sleep (based on an algorithm that interprets ambient light, sound and lack of movement) and how social you are (based on how much you are talking during the day – again based on an algorithm that measures primarily sound).
Of course, all of this could be scary too. This application, since it was developed by university researchers, is probably not about Big Brother, but about helping people keep track of mood rhythms. 
Another interesting aspect of the project, is that the application is part of a larger project (Open mHealth) which is trying to develop an open source framework for integrating health related data (with your permission) so that, for example, this data could be matched with data from your FitBit or Up device (also measuring activity) and perhaps the application that you use to track food and diet and then all of that data could be used to provide you with information about how to live a healthier life.
Open mHealth was developed by UCSF health researchers. Some of you may want to check out more information about Open mHealth here.
In addition to MoodRhythms, there is another application that implements the Open mHealth standard that can be used by application developers and even tech savvy individuals to create custom surveys in either iPhones or Android phones – called ohmage (I don’t know, an homage to Open mHealth, where do these names come from?). Anyway, more information about ohmage is available here.
