A data collection module receives signals generated using at least one of an electromyography (EMG) sensor connected to a user, an electroencephalography (EEG) sensor connected to the user, an electrocardiogram (ECG) sensor connected to the user, and an oxygen saturation (SPO2) sensor connected to the user. A mobile computing device is implemented independently of the data collection module and communicates with the data collection module. The mobile computing device includes a processor and a tangible computer readable medium including a sleep study application embodied as code for: selectively prompting the data collection module to store data samples generated based on the signals； receiving the data samples from the data collection module； and transmitting sleep study data including the data samples to a first data server. The mobile computing device further includes a communications module that wirelessly downloads the sleep study application from a second data server.
