A system for development of an algorithm for analysis of sensor data includes one or more wearable sensor devices, a smart device, and a cloud computing platform. The sensors in the wearable sensor device produce sensor data (e.g., physiological data) from a user that can be processed by a software algorithm in the wearable sensor device or by a connected smart device (e.g., a smartphone) via cloud computing, producing an algorithm output. The raw sensor data along with other information, such as the algorithm output and sensor data features can be sent to the cloud computing platform for storage and to enable developers to access the data in order to modify the software algorithms. The wearable sensor device can be configured to send more or less data to the cloud computing platform according to the performance of the software algorithm.
