The paper presents a smartphone application for monitoring physical activity and mental stress. The application utilizes sensor data from a wristband and/or a smartphone, which can be worn in various pockets or in a bag in any orientation. The presence and location of the devices are used as contexts for the selection of appropriate machinelearning models for activity recognition and the estimation of human energy expenditure. The stress-monitoring method uses two machinelearning models, the

The evaluation showed that we recognize a wide range of atomic activities with an accuracy of 87 %, and that we outperform the state-of-the art consumer devices in the estimation of energy expenditure. In stress monitoring we achieved an accuracy of 92 % in a real-life setting.
