**Note for cloning project: BioZen used to contain three sub-modules. Checking it out put the sub-modules as children to BioZen when they should be siblings (because other projects use them) To obtain all of the code for BioZen you must clone the following repositories: (This module)

BioZen is one of the first mobile applications to provide users with live biofeedback data from multiple wearable body sensors covering a range of biophysiological signals, including electroencephalogram (EEG), electromyography (EMG), galvanic skin response (GSR), electrocardiogram (ECG or EKG), respiratory rate, and temperature biofeedback data and display it on a mobile phone.

Using BioZen requires compatible biosensor devices (see listing below). These devices and BioZen are not designed or intended for psychological therapy or medical treatments.

BioZen can display several brain wave bands (Delta, Theta, Alpha, Beta, and Gamma) separately, as well as combinations of several bands using algorithms that may indicate relevant cognitive states, such as meditation and attention. BioZen features a meditation module that represents biometric information with user-selectable graphics that change in response to the user's biometric data.
