Abstract: A method and apparatus for testing and monitoring of personal, hyper-local chemical composition or environmental conditions is accomplished when a user or group of users gather data utilizing the combination of a sensor-extensible apparatus attached to one or more mobile communications devices, employing the associated mobile computing operating systems and network, in order to capture and transmit the relevant data to a cloud computing complex for storage, analysis and reporting. The cloud computing complex is configured to validate data by gathering corroborating evidence of location and reading accuracy, and provide a recommendation to a user or group of users within a threshold confidence level.
